Summary:
Change eden_store_util to take a subcommand argument, and define 3 separate
subcommands: "gc", "clear", and "compact"
The "gc" was the old default behavior. The "clear" and "compact" subcommands
simply clear cached entries and compact the storage, respectively.
This also adds a `--keySpace` argument. If this argument is specified the
command will process only this single key space, instead of all key spaces.

Summary:
This moves some logic from the RocksHandles class up to RocksDbLocalStore.
The main thing moved here is the logic to automatically try and repair the DB
if opening fails. This will make it easier in a subsequent diff to make the
repair logic a bit smarter and more aware of our column family semantics.
This keeps RocksHandles a pretty dumb wrapper around the RocksDB object and
column family handles, whose only purpose is to manage destroying these two
things in the correct order.

Summary:
Move this utility from eden/fs/service to eden/fs/store, and rename it to
`eden_store_util`.
I originally put it in the `service` subdirectory since it depends on library
code from `service/`, and most of the other code in `store/` shouldn't depend
on code in `service/`. However logically it makes sense to be in the `store/`
directory.
I plan to update in the future to be able to perform some additionally utility
operations besides just garbage collection, so rename it to the more generic
`eden_store_util` name.

Add a new class to manage access to the .eden state directory, and move some
logic for managing this director from the `EdenServer` class and into this new

This is largely just a first step. In the future I think we should move
additional functionality into this class. For instance, logic to determine
the correct local store type and logic to load the checkout map from
config.json. In the future it probably also make sense to move this class
from the `service` library into a slightly lower-level library (perhaps
`config` or `store`).

Summary:
This effectively reverts D14452214, which caused Eden to write an `id` entry
to each RocksDB column family and then flush the column family each time
edenfs started.
There was relatively little benefit to this in practice. It only matters in
cases where the RocksDB column families never had enough data written to them
to get flushed automatically and then a repair is required.
On the other hand it does have some material downsides: it flushing the column
families can be fairly expensive, and can require a substantial amount of free
disk space. This flush caused some users to not be able to start up edenfs
when they did not have enough free disk space.

Summary:
Change the `eden gc` implementation to use RocksDB's `DeleteFilesInRange()`
function, as well as its new-ish `DeleteRange()` method.
This makes the garbage collection much faster, and also require much less free
disk space than previously.
`DeleteFilesInRange()` asks RocksDB to simply delete all SST files from disk
if they only contain keys in the specified range. Since the range we specify
should include all keys in the DB this should simply drop all SST files for
this column family.
We also call `DeleteRange()` after this, just in case. This API is relatively
recent, and writes a single tombstone saying that the specified range has been
deleted.

Make these situations easier to debug by counting how many requests EdenFS makes to 'hg debugedenimporthelper'. These counters let us answer questions such as the following:
* When performance sucks, is EdenFS is making a lot of requests or only a few requests? I.e. is Hg slow at responding or is EdenFS very demanding?
* Does a recent performance issue correlate with EdenFS communicating with 'hg debugedenimporthelper'?
* Which engineers are outliers having orders of magnitude more 'hg debugedenimporthelper' requests than p50 engineers?
We could get fancier with these counters and include the number of bytes received, the duration of the request, etc. For now, just having a request count is useful.

Summary:
Ensure that the `TreeInode::createImpl()` code always releases the contents
lock at the end of the scope that was intended to signify the critical
section. Previously this was only unlocked when returning from this scope
successfully.
In particular, the old behavior could deadlock:
- We first created the new child inode.
- If saveOverlayDir() failed, we would throw an exception, causing us to not
release the directory lock yet.
- As we returned in the exception case, the local `inode` variable would be
destroyed before the `contents` argument, causing us to release the child
InodePtr's refcount before releasing the parent directory's lock. Because
we were the only user of the child inode we would end up needing to acquire
the parent inode's content's lock to check if it was unlinked.
This fixes the code to ensure that we always release the tree's contents lock
before the child inode becomes unreferenced.
