Summary:
We've seen a case where a large `hg update` was taking an absurdly long time in
`ObjectStore::getTree` but the telemetry was showing us that most of the time
wasn't spent fetching trees from Mercurial! The suspicion is that most of the
time was spent in the LocalStore but with no evidence to prove it.
Let's thus add some timing telemetry to various LocalStore read requests to
fill this gap.

Summary: Let's use this same pattern of delayed open across all the local stores so to keep things simple.

Summary:
opening the localstore can delay starting up the EdenFS server. I don't think
we use the Sqlite LocalStore any where (though we use RockDB for the overlay).
But I am going to allow the RockDbLocalStore to use a delayed open pattern, so
might as well teach sqlite to work this way to.

Summary:
The `LocalStore` constructor was updated to accept a `ReloadableConfig`
argument in D12949577, but this was never used anywhere. Remove it for now to
help simplify the code. If we do want to add it back in the future I think we
should make it required, rather than allowing a null config to be specified.

Summary:
This makes it possible to change configuration options
for the LocalStore while the server is running.
As you'll see in the next diff, our current layering makes using
the config a bit more awkward, but at least this diff doesn't
look gross :-p
This diff doesn't introduce any new functionality or configuration.

Summary:
Add the beginnings of an eden gc command. Today it's equivalent to
`eden debug clear_local_caches` followed by `eden
debug_compact_local_storage`, except that it compacts each column as
they're cleared to minimize peak disk consumption.
Eventually, it will also unload in-memory inodes, flush data from the
overlay, and clear the kernel's VFS cache too.

Summary:
Adds a SQLite storage implementation and makes it the
default engine for integration tests; this requires fewer resources
to run and the integration tests thus run faster and more reliably.
In the future we may add a configuration option to remember the
storage engine that was used as it is currently not "safe" to switch
from one to the other because the hgproxyhash data cannot be
recreated without re-importing a revision.
