Summary: Use `ServerIdentityMiddleware` from `gotham_ext` in the EdenAPI server to provide server information in the HTTP response headers returned by the server. This is useful for debugging.

Summary:
This makes it possible to use `Bytes` for mmap buffers.
The changes are because `minibytes::Bytes` does not implement `From<&[u8]>`
with the intention to make slice copy explicit.

EdenFS will now be able to fetch blobs directly from memcache. This won't have
any big benefits as no blobs are in memcache right now, but over time, this

Summary:
Everytime a cache miss is seen, the data fetched from the server will be sent
directly to memcache for future use. Unfortunately, doing so in a blocking
manner severely impact the overall fetching speed from the server. Since
memcache is purely an optimization, we can afford to send data to it
asynchronously.
Let's move as much as possible of the code to a background thread to reduce the
overhead of memcache.

Summary:
Even when memcache would be able to prefetch everything, this would always call
into the underlying remote store with an empt key set. For things like `hg
prefetch` and a large number of keys, the effect of doing that is minimum, but
for EdenFS or `hg log -p`, the roundtrip to the server for every file/revision
would add a significant amount of overhead. Let's simply stop iterating when we
no longer need to fetch anything.

Summary:
We never actually enabled it in production, and our new storage (ex. metalog,
indexedlog) are SIGKILL-safe. Only the changelog (revlog) might be subject to
double Ctrl+C issues. And we have debugfixcorrupt which can fix changelog
corruptions. So nointerrupt becomes less important.
The direct motivation is the test has been too flaky recently (and it's hard to
reproduce locally).

Summary:
This commit causes a desktop notification to be shown if we generate
EIO or ETIMEDOUT responses via fuse; the prompt is intended to make it obvious
to the user that they need to connect to the VPN.
The commit by itself doesn't show a notification, it allows configuring a
command that can be run to do something to show a notification.
The test plan includes one such configuration for our corp environment.
* It doesn't trigger for thrift-originated downloads (eg: prefetch), only for
VFS operations through FUSE.
* Ideally we'd know exactly when we have a network related error in the store
code and use that to trigger the notification. However, we have a rather
convoluted set of importers and fallbacks today, one of which is interpreting
a generic response returned from a pipe, so it is not especially clear
exactly where we should locate the logic
