1e161d2ed1 Initial benchmarks for caching. Closes #3530
These aren't suitable e.g. for running in CI since some take far too
long (and an impossibly long-time when running under criterion's normal
bootstrapping sampling regime.

We might try to improve this ourselves:
 https://github.com/bos/criterion/issues/218

An initial summary analysis will be in #3530.

421a182f64 export metadata without nulls, empty arrays & default values (#3393)
* export metadata without nulls, empty arrays
* property tests for 'ReplaceMetadata' using QuickCheck
-> Derive Arbitrary class for 'ReplaceMetadata' dependant types

* reduce property test cases number to 30
QuickCheck generates the `ReplaceMetadata` value really large
for higher number test cases. Encoded JSON for such values is large and
consumes more memory. Thus, CI is giving up while running property
tests.

* circle-ci: Add property tests as saperate job
* add no command mode to tests
* add yaml.v2 to go mod
* remove indirect comment for yaml.v2 dependency

c7a2320456 Implemented graceful shutdown for HTTP requests (close #2698) (#2717)
* Listens for SIGTERM as the termination signal
* Stops accepting new connections once the signal is received
* Waits for all connections to be drained, before shutting down
* Forcefully kills all pending connections after 30 seconds

Currently this does not send a close message to websocket clients, I'd
like to submit that change as a separate pull request, but at least this
solve my biggest concern which is not getting confirmation for mutations
while restarting the server.

02ae91c64d Increase idle GC interval to workaround CPU leak issue (#2581)
This seems to resolve the issue locally (and has worked in the past),
but it's not clear what exactly is going on here (in particular, why
this should resolve what looks like a memory leak). It certainly seems
like a GHC issue of some sort.

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.

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.

5f274b5527 fix mutation returning when relationships are present (fix #1576) (#1703)
If returning field contains nested selections then mutation is performed in two steps
1. Mutation is performed with returning columns of any primary key and unique constraints
2. returning fields are queried on rows returned by selecting from table by filtering with column values returned in Step 1.

Since mutation takes two courses based on selecting relations in returning field, it is hard to maintain sequence of prepared arguments (PrepArg) generated while resolving returning field. So, we're using txtConverter instead of prepare to resolve mutation fields.

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.

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.
