Summary:
This is a follow-up to D27093942 (59b8287c85). But D27093942 (59b8287c85) forgot one `read_log` spot, making it
possible to lose data.

Summary:
There are a few abstractions in this that make it a little hard to
have different behavior between the download & upload paths.
This makes it hard to have different behavior for the two. It's a bit of a
problem right now in the sense that we end up doing things like sending a
Content-Length on a GET, but the reason I'm changing it is because I want to
chunk downloads and that requires having different logic in the upload &
download paths.
As part of doing this, I also moved a bunch of parameters away from
HttpLfsRemote and into HttpOptions, which makes the function signatures a
little more manageable.

Summary:
This will let us better load balance across our clients by having them send
requests that are a fixed size. Indeed, right now, load imbalanced between
our hosts seem to be largely attributable to the fact that some hosts are
responsible for a few 150MB+ blobs, whereas others have none of those.
The motivation here is to let clients query us by range. Then, we can just have
clients fetch e.g. ~40MB at a time, and route those to different hosts, thus
eliminating said load imbalance.

Summary:
I'd like to add support for Range queries in LFS. In HTTP, the range header
isn't start + size, it's start / end, so I'll need a slightly lower API. This
makes that possible.
Note: Range should have a private constructor, because otherwise we'll get
errors if start > end. Hence the `Range` / `RangeInner` here.

Summary:
Remove use of `#[async_trait]` in the new storage API, and eliminate the outer Future on the `fetch_stream` and `write_stream` methods, which was not used. The methods are now normal trait methods, which accept and return a stream.
It's possible we'll want to make these methods `async` again in the future, but until this this is more ergonomic, faster (one less layer of indirection), and avoids some of the type system limitations of `#[async_trait]`.

Summary:
Introduce `FilterMapStore` combinator to support cases like LFS, where values of the same type may or may not be supported by a given store implementation.
Use `FilterMapStore` in Python bindings to prevent LFS files from being accidentally written to the non-LFS indexedlog.
With this change, the new storage API should be safe to use without corrupting local storage.

Summary:
Introduce `WriteError` type (similar to `FetchError` for reads) to support strongly-typed write errors. Eventually we'll probably want this type to carry the value that we tried to write (to allow write fallbacks, retries, etc) and perhaps add more enum variants (rejects, unavailable, etc).
Introduce `ReadWriteStore` trait for stores that support both reading and writing. This trait is automatically implemented for types which implement `ReadStore` and `WriteStore` with the same key and value types. This trait is intended to be used via the `BoxedRWStore` trait object. This type will be used in the Python bindings when `FallbackCache` is extended to implement `WriteStore` (in a future change).

Summary:
Introduce newfilestore class in pyrevisionstore, which constructs a newfilestore (BoxedReadStore for files) and a corresponding `ContentStore` which share the underlying IndexedLog object and EdenApi client.
Modify remotefilelog to construct ContentStore via this new class.
Currently, no methods are provided for the newfilestore - it is meant to be passed back into Rust code, where you may call it's Rust methods as shown in the `test_newstore` method (which will be removed in the future).
Currently the `util` module is made public for access from pyrevisionstore. In the future, this will be replaced in favor of a `NewFileStoreBuilder` which handles these concerns internally.

Summary:
Split `FallbackStore` (which supports writing fallback fetches) into `FallbackCache` (which behaves the same) and `Fallback` (which doesn't support writing fallback fetches). This eliminates the `From<>` bound on `Fallback` which is nonsensical in some cases where we don't want writing.
Replace `write_store` and `write` fields with a single `Option<>` `write_store` in `FallbackCache`, which cleans up the code a bit.
Separate the "fallback value type", "preferred value type", "write value type", and "output value type" separately control the output value type independent of the preferred store.

Summary:
The problem appears when we have shared idmap moving ahead of the memory idmap
before we ever write to the memory idmap. In that case we would incorrectly
fetch last shared from the shared idmap. When that shared last entry is larger
than the cutoff we would try to assign ids starting from the shared entry. When
updating the IdDag it would assume that it has to insert all ids above the
cutoff but it would fail to resolve all ids exactly above the cutoff.
For example, MemIdMap is empty, cutoff is 5, shared idmap last entry is 7. We
asign 8-10 then the IdDag tries to search for 5-10 and fails to resolve 5.
This function was not updated after adding cutoff to OverlayIdMap in an earlier
diff.

Summary:
While Mononoke should support pushing large commits, it's not clear if we need
(or want) to support pushing a lot of commits. At the very least pushing lots of commits at the same
time can create problems with derivation, but there could be more places that might break.
Besides there's usually an easy way to work around that i.e. sqush commits or push in small batches.
If we ever need to import a lot of it we use tools like blobimport/repo_import,
so blocking pushing of lots of commits should be fine.

Summary:
Add an `edenapi.logdir` config option, which, when set, will cause the EdenAPI client to write a JSON version of every request it sends to the specified directory. This is intended for use when reproducing user issues (so that the developer can inspect and replay the requests that were sent).
The JSON request files can be directly given to the `edenapi_cli` or converted to CBOR using the `make_req` tool for manual testing with `curl`.
The approach right now is a bit simplistic, in that we just write a JSON file whenever the EdenAPI client makes a request. I'm open to suggestions on how to improve this. (For example, if there were a way for us to always have a record of the last N requests, that would be helpful for debugging user issues.)
