server: Pass EKG Metrics Store as argument to runHGEServer (#5560)
* Add ekg-core to build-executable .cabal

* Move creation of EKG Store to Main.hs

This helps to share metrics between pro and OSS and
helps surface the metrics from OSS in Datadog via
Pro.

server: pass http and websocket request to logging context (#5470)
* pass request body to logging context in all cases

* add message size logging on the websocket API

  this is required by graphql-engine-pro/#416

* message size logging on websocket API

  As we need to log all messages recieved/sent by the websocket server,
  it makes sense to log them as part of the websocket server event logs.
  Previously message recieved were logged inside the onMessage handler,
  and messages sent were logged only for "data" messages (as a server event log)

* fix review comments

More robust forking, exception safety. Closes #3768 (#3860)
This is the result of a general audit of how we fork threads, with a
detour into how we're using mutable state especially in websocket
codepaths, making more robust to async exceptions and exceptions
resulting from bugs.

Some highlights:
- use a wrapper around 'immortal' so threads that die due to bugs are
  restarted, and log the error
- use 'withAsync' some places
- use bracket a few places where we might break invariants
- log some codepaths that represent bugs
- export UnstructuredLog for ad hoc logging (the alternative is we
  continue not logging useful stuff)

I had to timebox this. There are a few TODOs I didn't want to address.
And we'll wait until this is merged to attempt #3705 for
Control.Concurrent.Extended

f506cb397f Log time spent consuming request bytes from socket. Closes #3547
Add a new 'request_read_time' to the logging record.

We also use 'withElapsedTime' to get proper monotonic clock for
'query_execution_time' as well.

Brandon Simmons
58ef316118 Add request timings and count histograms to telemetry. Closes #3552
We upload a set of accumulating timers and counters to track service
time for different types of operations, across several dimensions (e.g.
did we hit the plan cache, was a remote involved, etc.)

Also...

Standardize on DiffTime as a standard duration type, and try to use it
consistently.

See discussion here:
https://github.com/hasura/graphql-engine/pull/3584#pullrequestreview-340679369

It should be possible to overwrite that module so the new threadDelay
sticks per the pattern in #3705 blocked on #3558

Rename the Control.Concurrent.Extended.threadDelay to `sleep` since a
naive use with a literal argument would be very bad!

We catch a bug in 'computeTimeDiff'.

Add convenient 'Read' instances to the time unit utility types. Make
'Second' a newtype to support this.

  threads
- Remove eventlog instrumentation
- Don’t rebuild the schema cache again after running a query that needs
  it to be rebuilt, since we do that explicitly now.
- Remove some redundant checks, and relocate a couple others.

4facb3c780 remove support for query templates (#2560)
query templates is a little known feature that lets you template rql
queries and serve them as rest apis. This is not relevant anymore
given the GraphQL interface and getting rid of it reduces the dev
time when adding features in few subsystems.

This feature has never been used outside hasura's internal projects or
documented or exposed through console and hence can safely be removed.

bundle console assets into server (close #516, close #521, close #2130) (#2192)
This PR builds console static assets into the server docker image at `/srv/console-assets`. When env var `HASURA_GRAPHQL_CONSOLE_ASSETS_DIR=/srv/console-assets` or flag `--console-assets-dir=/srv/console-assets` is set on the server, the files in this directory are served at `/console/assets/*`.

The console html template will have a variable called `cdnAssets: false` when this flag is set and it loads assets from server itself instead of CDN.

The assets are moved to a new bucket with a new naming scheme:

```
graphql-engine-cdn.hasura.io/console/assets/
   /common/{}
   /versioned/<version/{}
   /channel/<channel>/<version>/{}
```

Console served by CLI will still load assets from CDN - will fix that in the next release.

a21f6cd648 introduce v1/graphql (fix #1368) (#2064)
Changes compared to `/v1alpha1/graphql`

* Changed all graphql responses in **/v1/graphql** endpoint to be 200. All graphql clients expect responses to be HTTP 200. Non-200 responses are considered transport layer errors. 

* Errors in http and websocket layer are now consistent and have similar structure.

e32f5a1fb1 sync metadata cache across multiple instances connected to same db (closes #1182) (#1574)
1. Haskel library `pg-client-hs` has been updated to expose a function that helps listen to `postgres` notifications over a `channel` in this [PR](https://github.com/hasura/pg-client-hs/pull/5)
2. The server records an event in a table `hdb_catalog.hdb_cache_update_event` whenever any `/v1/query` (that changes metadata) is requested. A trigger notifies a `cache update` event via `hasura_cache_update` channel
3. The server runs two concurrent threads namely `listener` and `processor`. The `listener` thread listens to events on `hasura_cache_update` channel and pushed into a `Queue`. The `processor` thread fetches events from that `Queue` and processes it. Thus server rebuilds schema cache from database and updates.

02d80c9ac6 read cookie while initialising websocket connection (fix #1660) (#1668)
* read cookie while initialising websocket connection (fix #1660)

* add tests for cookie on websocket init

* fix logic for tests

* enforce cors, and flag to force read cookie when cors disabled

  - as browsers don't enforce SOP on websockets, we enforce CORS policy
  on websocket handshake
  - if CORS is disabled, by default cookie is not read (because XSS
  risk!). Add special flag to force override this behaviour

* add log and forward origin header to webhook

  - add log notice when cors is disabled, and cookie is not read on
  websocket handshake
  - forward origin header to webhook in POST mode. So that when CORS is
  disabled, webhook can also enforce CORS independently.

* add docs, and forward all client headers to webhook

199a24d050 add support for multiple domains in cors config (close #1436) (#1536)
Support for multiple domains (as CSV) in the `--cors-domain` flag and `HASURA_GRAPHQL_CORS_DOMAIN` env var.

Following are all valid configurations (must include scheme and optional port):
```shell
HASURA_GRAPHQL_CORS_DOMAIN="https://*.foo.bar.com:8080"
HASURA_GRAPHQL_CORS_DOMAIN="https://*.foo.bar.com, http://*.localhost, https://example.com"
HASURA_GRAPHQL_CORS_DOMAIN="*"
HASURA_GRAPHQL_CORS_DOMAIN="http://example.com, http://*.localhost, http://localhost:3000, https://*.foo.bar.com, https://foo.bar.com"
```

**Note**: top-level domains are not considered as part of wildcard domains. You have to add them separately. E.g - `https://*.foo.com` doesn't include `https://foo.com`.

The default (if the flag or env var is not specified) is `*`. Which means CORS headers are sent for all domains.

local console during development (#1252)
* console now works on local builds of the server

1. local console assets can be served at /static/ by a build time flag
'local-console'. This can be set with stack as follows:
   `stack build --flag graphql-engine:local-console`
2. the --root-dir option is removed which was used as a temporary hack
for serving graphiql
3. remove server's graphiql source code

75090d51b9 jwt config now takes a jwk url (close #465) (#527)
JWT config now takes an optional jwk_url parameter (which points to published JWK Set). This is useful for providers who rotate their JWK Set.

Optional jwk_url parameter is taken. The published JWK set under that URL should be in standard JWK format (tools.ietf.org/html/rfc7517#section-4.8).

If the response contains an Expires header, the JWK set is automatically refreshed.

b2f88ff28a add support for jwt authorization (close #186) (#255)
The API:
1. HGE has `--jwt-secret` flag or `HASURA_GRAPHQL_JWT_SECRET` env var. The value of which is a JSON.

2. The structure of this JSON is: `{"type": "<standard-JWT-algorithms>", "key": "<the-key>"}`
`type` : Standard JWT algos : `HS256`, `RS256`, `RS512` etc. (see jwt.io).
`key`:
  i. Incase of symmetric key, the key as it is.
  ii. Incase of asymmetric keys, only the public key, in a PEM encoded string or as a X509 certificate.

3. The claims in the JWT token must contain the following:
  i. `x-hasura-default-role` field: default role of that user
  ii. `x-hasura-allowed-roles` : A list of allowed roles for the user. The default role is overriden by `x-hasura-role` header.

4. The claims in the JWT token,  can have other `x-hasura-*` fields where their values can only be strings.

5. The JWT tokens are sent as `Authorization: Bearer <token>` headers.

---
To test:
1. Generate a shared secret (for HMAC-SHA256) or RSA key pair.
2. Goto https://jwt.io/ , add the keys
3. Edit the claims to have `x-hasura-role` (mandatory) and other `x-hasura-*` fields. Add permissions related to the claims to test permissions.
4. Start HGE with `--jwt-secret` flag or `HASURA_GRAPHQL_JWT_SECRET` env var, which takes a JSON string: `{"type": "HS256", "key": "mylongsharedsecret"}` or `{"type":"RS256", "key": "<PEM-encoded-public-key>"}`
5. Copy the JWT token from jwt.io and use it in the `Authorization: Bearer <token>` header.
