Summary:
This stack updates eden to be able to check all of the locations that able
users certificate may reside.
There can be multiple places where a cert may reside (we cant always
definitively choose one place to look based on the platform). Thus we
need to be able to configure multiple locations for certs in our eden
config.
Thus we need to be able to parse a list of options for a key in our config
parsing.
**Disclaimer this is really icky**
Our `FieldConverter` interface takes a string to parse. So this means
that after parsing the config file for each value we have to re-serialize it
into a string to pass it in here. Previously we only supported string and
bool values so this re-serialization was not too terrible. Now that we want
to support arrays this re-serialization is extra gross. To minimize the grossness,
I am reusing cpptoml for serializing / deserializing around the `FieldConverter`
interface.
Long term it would be better if FieldConverter took a cpptoml::base or
something more generic instead of a string so we dont have to do this.
But that will be a big refactor, and I don't currently have bandwidth for it :(

Summary:
We've often had cases where we need to nuke peoples caches for various
reasons. It's a hug pain since we haven't a way to communicate with all hg
clients. Now that we have configerator dynamicconfigs, we can use that to reach
all clients.
This diff adds support for configs like:
```
[hgcache-purge]
foo=2020-08-20
```
The key, 'foo' in this case, is an identifier used to only run this purge once.
The value is a date after which this purge will no longer run. This is useful
for bounding the damager from forgetting about a purge and having it delete caches
over and over in the future for new repos or repos where the run once marker
file is deleted for some reason.

Summary:
Similarly to FuseRequestContext, this will be allocated whenever ProjectedFS
calls onto EdenFS to keep track of timing, stats, etc.
For now, this just holds the callback data passed in, we need to copy it as
ProjectedFS will deallocate it when the EdenFS callback returns, but since we
intend to complete these asynchronously, the callback data needs to outlive the
callback, hence the copy. It's likely that this is copying too much, and only
part of it actually needs to be copied, this will be tackled later.

Summary:
Currently getbundle implementation works this way: it accepts two list of
changesets, a list of `heads` and a list of `common`. getbundle needs to return
enough changesets to the client so that client has `heads` and all of its
ancestors. `common` is a hint to the server that tells which nodes client
already has and doesn't need sending.
Current getbundle implementation is inefficient when any of the heads have a low
generation number but also we have a lot excludes which have a high generation
number. Current implementation needs to find ancestors of excludes that are
equal or lower than generation of this head with a low generation number.
This diff is hacky attempt to improve it. It does it by splitting the heads
into heads with high generation numbers and heads with low generation numbers,
sending separate getbundle requests for each of them and then combining the
results.
Example
```
O <- head 1
|
O <- exclude 1
|
... O <- head 2 <- low generation number
| |
O O <- exclude 2
```
If we have a request like `(heads: [head1, head2], excludes: [exclude1, exclude2])` then this optimization splits it into two requests: `(heads: [head1], excludes: [exclude1, exclude2] )` and `(heads:[head2], excludes:[exclude2])`, and then combines the results. Note that it might result in overfetching i.e. returning much more commits to the client then it requested. This might make a request much slower, and to combat that I suggest to have a tunable getbundle_low_gen_optimization_max_traversal_limit that prevents overfetching.

Summary:
shed/sql library used mainly to communicate with Mysql db and to have a nice abstraction layer around mysql (which is used in production) and sqlite (integration tests). The library provided an interface, that was backed up from Mysql side my raw connections and by MyRouter.
This diff introduces a new backend - new Mysql client for Rust.
New backend is exposed as a third variant for the current model: sqlite, mysql (raw conn and myrouter) and mysql2 (new client). The main reason for that is the fact that the current shed/sql interface for Mysql
(1) heavily depends on mysql_async crate, (2) introduces much more complexity than needed for the new client and (3) it seems like this will be refactored and cleaned up later, old things will be deprecated.
So to not overcomplicate things by trying to implement the given interface for the new Mysql client, I tried to simplify things by adding it as a third backend option.

Summary: This diff refactors the tool to use changeset_ids instead of changesets, since the functionalities of the tool always use the ids over the changesets. For process recovery (next steps) it's more ideal to save the changeset_ids, since they are simpler to store. However, if we used changesets in the tool, we would need to load them with the saved ids just to only use the ids throughout the process. Therefore, this loading step becomes redundant and we should simply use the ids.

Summary:
Add a new `HandlerInfo` struct that can be inserted into the request's `State` by each handler to provide information about the handler to post-request middleware. (This includes things like which handler ran, which repo was queried, etc.)
A note on design: I did consider adding these fields to `RequestContext` (similar to how it's done in the LFS server), but that proved somewhat problematic in that it would require using interior mutability to avoid forcing each handler to borrow the `RequestContext` mutably (and therefore prevent it from borrowing other state data). The current approach seems preferable to adding a `Mutex` inside of `RequestContext`.
