Summary:
We want to have a shared pool of `HgImporter` across different threads, but that would require `HgImporter` is safe to be *passed* between threads. (This is not making `HgImporter` entirely thread safe.)
However, `HgImporter` currently holds a pointer to the thread local fb303 counter. This diff pushes down `EdenStats` so we only access the thread local stats variable when we need to add counters. This might be a little slower but it does make it safer.

Summary:
Troditionally, ObjectStore relied on HgBackingStore writing directly
to LocalStore in order to cache trees. This had the unfortunate side
effect that other backing store implementations did not benefit from
tree caching.

Summary:
This diff turns the return type of `BackingStore::getBlob` from `folly::Future` into `folly::SemiFuture` to prevent executor leaks.
This also enable us to remove the need of holding `serverThreadPool` from backing stores.
----
**Changes**
* `ObjectStore` now needs to hold a `folly::Executor::KeepAlive` that is used to turn `SemiFuture`s it gets from backing stores into `Future`.
* Signature changes of the implementations of `BackingStore` class.
* For tests, I chose to use `QueuedImmediateExecutor` in place of `UnboundedQueueExecutor` as it will basically execute tasks inline. I'm concerned introducing thread pool executor in tests may turn tests flaky.

* 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?

Summary:
We updating the encoding that mercurial uses for storing paths to UTF-8.
The current step is preventing files that have invalid names from being
committed. To that end we are updating the HgPrefetch test to submit
valid file names (valid UTF-8). This allows us to start using UTF-8
encoded string for the internal representation of file paths.
Doing encoding transformation between internal storage and system locale will
be implemented later. Normalization should also be handled at that point.

Summary:
If TreeInode::startLoadingInode() is in progress, and EdenServer::startTakeoverShutdown() is called, edenfs can deadlock:
1. Thread A: A FUSE request calls TreeInode::readdir() -> TreeInode::prefetch() -> TreeInode::startLoadingInode() on the children TreeInode-s -> RocksDbLocalStore::getFuture().
2. Thread B: A takeover request calls EdenServer::performTakeoverShutdown() -> InodeMap::shutdown().
3. Thread C: RocksDbLocalStore::getFuture() (called in step 1) completes -> TreeInode::inodeLoadComplete(). (The inodeLoadComplete continuation was registered by TreeInode::registerInodeLoadComplete().)
4. Thread C: After TreeInode::inodeLoadComplete() returns, the TreeInode's InodePtr is destructed, dropping the reference count to 0.
5. Thread C: InodeMap::onInodeUnreferenced() -> InodeMap::shutdownComplete() -> EdenMount::shutdown() (called in step 2) completes -> EdenServer::performTakeoverShutdown().
6. Thread C: EdenServer::performTakeoverShutdown() -> localStore_.reset() -> RocksDbLocalStore::~RocksDbLocalStore().
7. Thread C: RocksDbLocalStore::~RocksDbLocalStore() signals the thread pool to exit and waits for the pool's threads to exit. Because thread C is one of the threads managed by RocksDbLocalStore's thread pool, the signal is never handled and RocksDbLocalStore::~RocksDbLocalStore() never finishes.
Fix this deadlock by executing EdenServer::shutdown()'s callback (in EdenServer::performTakeoverShutdown()) on a different thread.

Summary:
Throw a slightly nicer error message if the hg import helper exits before
returning a `CMD_STARTED` response or an error response.
When switching from the `hg_import_helper.py` script to the
`hg debugedenimporthelper` subcommand we are slightly more likely to encounter
errors during startup. For instance, if the repository path was not a valid
repository the `hg_import_helper.py` code would send an error message back
that the `HgImporter.cpp` code could parse. However, we unfortunately can't
catch errors loading the repository the same way when using an `hg`
subcommand. If it fails to load the repository it will simply print an error
message to stderr and then bail out before it invokes the
`debugedenimporthelper` code.

Summary:
This reverts the change in D14188312 that moved `hg_import_helper.py` from
`bin/` to `libexec/eden/`, and instead updates edenfs to look for
`hg_import_helper.py` at `../../bin/hg_import_helper.py`
We cannot remove `hg_import_helper.py` from `/usr/local/bin` without breaking
existing running `edenfs` daemons as they will continue to look for
`hg_import_helper.py` in this location.
Rather than keeping a copy in both `bin/` and `libexec/eden` it seems better
to simply update edenfs so that it can correctly find `hg_import_helper.py`
even when edenfs itself has been installed in `libexec/eden/`

Summary:
Now that `hg debugedenimporthelper` has been released for
a little while, we can remove the bundled implementation of it from
the eden release.
However, we cannot remove the script itself as there are users
with long running edenfs instances that pre-date the knowledge
of `hg debugedenimporthelper`. So, as a compatibility shim,
this diff redirects `hg_import_helper.py` and has it exec the
command in mercurial.
For extra fun, our own integration tests rely on being able
to import `hg_import_helper.py` and override portions of it,
so we cannot remove its implementation from the codebase just
yet either.
So this diff:
* Introduces `proxy_import_helper.py` which execs `hg debugedenimporthelper`
* Installs `proxy_import_helper.py` as `hg_import_helper.py` in the rpm
* Leave `hg_import_helper.py` as-is in the tree for now.

Summary:
in D13970332 we want to allow using `hg.real` to run the
import helper that is embedded into mercurial, but we don't know
the full path, so we need to resolve it from the environment.
`folly::Subprocess` has `usePath` option, but it is not compatible
with also overriding the environment for a child process.
The easiest short term thing to do is to resolve the path ourselves
using this simple function call.
I've also added the path to `hg.real` that is used on our mac systems
to the PATH we pass down to `edenfs` when starting eden.
Longer term we want to better encapsulate how we resolve and start
the import helper, but for now this unblocks starting eden on the
mac.

Summary:
D13853115 adds `edenscm/` to `sys.path` and code still uses `import mercurial`.
That has nasty problems if both `import mercurial` and
`import edenscm.mercurial` are used, because Python would think `mercurial.foo`
and `edenscm.mercurial.foo` are different modules so code like
`try: ... except mercurial.error.Foo: ...`, or `isinstance(x, mercurial.foo.Bar)`
would fail to handle the `edenscm.mercurial` version. There are also some
module-level states (ex. `extensions._extensions`) that would cause trouble if
they have multiple versions in a single process.
Change imports to use the `edenscm` so ideally the `mercurial` is no longer
imported at all. Add checks in extensions.py to catch unexpected extensions
importing modules from the old (wrong) locations when running tests.
