Summary:
We have seen that eden will unexpectedly fetch data, we want to know why.
This adds the plumbing to interact with edens current logging to be able to
log when eden fetches data from the server and what caused eden to do this
fetch. Later changes will use the classes created here to log the cause of data
fetches.

Summary:
Recently the server team added an un-used directory to test that eden would not
fetch these as a test for the upcoming repo merge. They saw that these files
were fetched a non trivial number of times. We want to know why eden is causing
these fetches.
This adds the pid and interface through which the client is interacting with eden to
ObjectFetchContext for this purpose. This information will be logged in later
changes.
note: currently this is only for fetches through Fuse (thrift interface to follow).

In following changes I will add logging in the HgQueuedBackingStore.
Ultimately we will want to move this logging to be closer to the data fetching
(in HgDatapackStore and HgImporter), but I plan to temporarily add logging to
the HgQueuedBackingStore to simplify so that we can more quickly roll out.

Summary:
On Windows (haven't verified on other platforms), ThreadLocalPtr don't appear
to be releasing resources when a thread die. This means that when the importer
thread dies, the actual importer (hg.real) would still run and use resources,
with no way of talking to it.
To fix this, let's manually reset it when the main thread function returns,
this forces the importer to be destroyed and therefore the various handles to
hg.real to be released, effectively terminating it.
I'm not sure if this is the proper fix, but delving into folly feels a bit
daunting. Keeping a TODO for later to go back to it and fix it properly in
folly.

Summary:
Previously we check if a request is a fuse request when we fetch anything from backing store, so we can collect number of fetches happened for each process in eden top.
This is creating a dependency from store to fuse, which is a little awkward. Instead, we could make `RequestData` a `ObjectFetchContext` and record the fetches when that happens.
Similarly in the future we should also have something equivalent in our Thrift layer.

Summary:
The CreateProcess API allows inheritable handles to be available in the spawned
process by passing a flag to it. What the documentation for this API leave to
the imagination is what happens when processes are spawned concurrently in
multiple threads and handles are opened and made inheritable while doing this.
The answer is obvious but the consequences aren't: they are inherited.
When anonymous Pipes are used, one end needs to be inheritable for the spawned
process to being able use it, but if one is created concurrently with spawning
a process, that other process may have an open handle to that unrelated pipe.
And since to detect that a pipe is closed, all handles to the other end needs
to be closed, this can lead to never being able to detect that it is closed...
This scenario is exactly what is happening in eden when spawning the Mercurial
process, and when one of these processes would die, eden would just hang trying
to write to the pipe, not knowing that the process was already gone. To unblock
eden, all the hg.real processes had to be killed, as this would close all the
pipe handles, and then eden would detect that the pipe was closed and re-spawn
Mercurial (only for the exact same thing to happen).
In order to fix this, we need to tell CreateProcess to only inherit the pipes
handles, and nothing else.

In order to start EdenFS automatically at boot, a template service was used
previously, but due to several issues, we decided to move away from it.
Thankfully microsoft supports several other ways of starting tasks at startup,
one of which is the "Task Scheduler" itself.
One of the weird part of the task scheduler is that there isn't a good way
to tell it to not show a console for a non-graphical application, and thus
plainly executing edenfsctl start in it would create a cmd window, which
would then disappear a couple of seconds later. To avoid this, a "graphical"
version of Python is used (pythonw.exe) to start edenfsctl.
