Summary:
When scrubbing to collect commit times for path info logging, its much easier to get correct commit times for manifests by walking from oldest changeset first. That way when any manifest/tree is discovered its from the closest changeset chunk to its creation.
Alternative would have been using the path data from linknode associated changesets to prune out which sub-manifests to walk when walking forward, which is more complicated and would require holding more state (or reloading changesets continuall)

Summary:
There have been a bunch of problems with the previous approach to scmstore, so I'm going to try to start simple, make it feature complete, and then add async integration and factor out generic functionality as appropriate.
This change contains a `TreeStore` implementation with a single, synchronous, batch read method (supporting local storage, memcache, and legacy fallback, with writing missing to cache).
Add `TreeStoreBuilder`, which duplicates the existing `TreeScmStoreBuilder`, which some changes that make it easier to use for this case. I intend to unify these in the future.
Add an inherent impl for `EdenApiTreeStore` that provides subset of the `BlockingEdenApi` trait, which eliminates the need to unpack this type into a different adapter as the old `scmstore` code does. This might not be the right approach here, in reality we only need a `(client: Arc<dyn EdenApi>, repo: String)` here for trees, and that + `ExtStoredPolicy` for files, so we could take the `EdenApiAdapter` approach here too. The only reason we have to do any of this is because when `pyrevisionstore` is called to construct `scmstore` / `contentstore`, all we have is `Arc<EdenApiTreeStore>`. We could also just make the `EdenApiRemoteStore` fields public, and access them through the `Arc`.
Add `add_mcdata` method to `MemcacheStore`, `impl TryFrom<Entry> for McData`, and `impl From<McData> for Entry` for convenience when working with `MemcacheStore` (so we don't need to manually unpack the type and build `Entry`, or manually build a fake `Delta` from `Entry` to write).

Summary:
Both `get_local_path` and `get_cache_path` take suffix as as `PathBuf`, even though they only ever use it as a reference. `get_local_path` also takes a reference to a `PathBuf`, even though it always clones it internally, and takes an `Option`, even though it just maps across the contents of the option.
I modified `get_local_path` to accept a `PathBuf` by move, which it uses directly, and to not take an `Option` (instead just calling `map` externally, removing some unnecessary unwraps), and for both functions to accept `impl AsRef<Path>` for suffix.

Summary:
Vertex is old. It no longer makes sense with the current structure. The main
issue is that the dag crate now has VertexName which may confuse readers at
first glance.
When Vertex was added DagId would have been confusing because we had structs
that were named Dag that did not use DagId directly. Those structures are now
renamed and DagId is consistently used for dag crate structures.
The IdMap database would still use the vertex name until someone runs a
migration to rename the column.
I am not 100% that this is needed, but it's a change that's been on my mind.

Summary:
Previously there were two different paths to HgChangeset. This diff unifies them, so that when walker state.rs is checking for a previous visit it will find that it happened.
For existing walks of changesets in the NewestFirst direction this wasn't causing a problem, however the next diff in stack adds support for OldestFirst walks. In the OldestFirst case the mismatch in paths to HgChangeset was leaving a deferred edge to visit when everything should have been visited in previous chunks.

Summary:
This updates hg to have a different amount of retry for backoffs requested by
the server and errors.
The rationale is that backoffs are fairly well understood and usually caused by
a surge in traffic where everybody wants the same data (in which case we should
be willing to wait to get it because there is literally no alternative),
whereas general errors aren't predictable in the same way.
We're now effectively at a point on the server side where _all_ our instances
have the exact same load, so if any server is telling you to backoff, that
pretty much guarantees that the whole tier has too much traffic to deal with.
This leaves us with two options:
- Tell clients to wait longer and smooth out the traffic surge.
- Add enough capacity that even our biggest surges don't result in _any_
throttling.
The latter is a bit unrealistic unrealistic given we routinely get egress
variations in excess of 5x (here's an example: https://fburl.com/ods/pidsrqnl),
so this does the former.
This also updates the client to tell the server how many attempts it has left
in addition to how many it used up so far. How many are left is more meaningful
for alerting!
Finally, it adds a bit of logging so that in debug mode you can see this
happening.
