Summary:
Previously if you `sudo umount -f fbsource-nfs` then try to
`eden mount fbsource-nfs`, the mount will fail because the EdenMount already
exists and is still running.
Let's properly unmount our selfs on a force unmount like we do for fuse.
There are two potential ways to detect a fource unmount: the UMNT call to the
mount deamon or the socket to the nfsd closing. The UMNT call is unreliable
(on Linux we do not get the UNMT call on `umount -l`), so this diff pursues the
socket closing option.
When the nfsd socket is closed we trigger the EdenMount unmounting process if
this has not already started.

With NFS, the server is stateless, and thus to support unlinking opened files,

Summary:
For non-UTF8 names, the PathComponent constructor would raise an exception, and
since that exception wasn't caught by the handler itself, it would bubble up to
the RPC server and a generic "server IO error" would be sent back to the
client. Since non-UTF8 names aren't a server error, but an invalid argument, we
should instead return a different error.
Unfortunately, EILSEQ isn't an error that an NFS server can return, instead
let's use EINVAL as the argument is clearly invalid.

Similarly to the work that kmancini did for the integration tests, this
enables the Mercurial integration tests to run against NFS. Only 3 tests are
failing due to 3 separate reasons: graceful restart isn't support, permissions
given to the clients are wrong, and a lifetime issue for the Nfsd3 object.
As a bonus, I've cleaned the code a bit since TreeOnly was the only supported
configuration (and will likely stay that way).

Summary:
An NFS client caches the attributes of files to avoid having to request these
very frequently. What this means is that a file changed by another client (or
by the server itself) may take some time to be reflected on the client, that
time depends on the attribute caching configuration of the mount point.
For EdenFS, files can changed in 2 ways:
- Either it is changed by the user via the mount point,
- Or the user runs an `hg update`
For the first one, the client will simply update its attributes appropriately,
but for the second one, the cached attributes will only be updated when the
user does opens the file, any calls to stat prior will return the old
attributes. Since EdenFS runs on the same host, we can force the attributes
caches to be discarded by simply issuing an open call on the file that changed.

This applies the formatting changes from black v21.4b2 to all covered
projects in fbsource. Most changes are to single line docstrings, as black

or files that previously triggered errors in black.
Any changes to code should be AST identical. Any test failures are likely
due to bad tests, or testing against the output of pyfmt.

Currently we have limited test coverage of the NFS code. Let's start running

This covers most of the tests, but a few tests do not use this decorator. See next
change.

Some test runner don't properly redirect stdout/stderr of nested processes, or
even direct writes to filedescriptors. On these, debugging a test failure is
almost impossible for EdenFS as we rely on the test output to be interleaved
with the EdenFS logs to understand what the daemon is doing.
To solve this, we can simply create a thread that redirects the output of
EdenFS to sys.std{out,err}.

Summary:
The world has moved on utf-8 as the default encoding for files and data, but
EdenFS still accepts non utf-8 filenames to be written to it. In fact, most of
the time when a non utf-8 file is written to the working copy, and even though
EdenFS handles it properly, Mercurial ends up freaking out and crash. In all of
these cases, non-utf8 files were not intentional, and thus refusing to create
them wouldn't be a loss of functionality.
Note that this diff makes the asumption that Mercurial's manifest only accept
utf8 path, and thus we only have to protect against files being created in the
working copy that aren't utf8.
The unfortunate part of this diff is that it makes importing trees a bit more
expensive as testing that a path is utf8 valid is not free.
