Using the same cache key across multiple jobs can cause issues if we make assumption about it's content (like installing tools if not hit on the cache).
During certain operation, macOS use some helper that send request to the mountpoint with `crtime` set to `0xffff83da4f80`. That value correspond to `-2_082_844_800u64` which is the difference between the date 1904-01-01 and 1970-01-01 because macOS epoch start at 1904 and not 1970. <macfuse/macfuse#1042> Fix awslabs#217

Currently the Filesystem trait forces only a single request dispatch loop, with the idea that a filesystem that wants to be concurrent can just spawn its own threads and dispatch operations on them itself. This works, but it's bad for performance, because it forces every request to bounce across threads. Instead, let's make the Filesystem trait use interior mutability. This allows us to spawn multiple dispatch threads that each block on the FUSE device, read a request, and immediately dispatch it without the bounce. Unfortunately there's not a good way for a trait to be variant in mutability, so this is a breaking API change. We'll need to think more carefully about how to upstream this change.

## Description of change fuser v0.15.0 added support for creating sessions from FUSE fd. I'm working on a PR to add this support to Mountpoint. We still need to open the FUSE device and call `mount` syscall in order to test this new behavior, and all this logic is already exists with `mnt::Mount`. We could just copy the logic from `mnt::Mount` - but since we already have this fork, making this change seemed fine to me. Maybe we can also consider upstreaming it. ## Does this change impact existing behavior? No ## Does this change need a changelog entry in any of the crates?

Our fuser fork emits a lot of warnings during builds, impacting our pull requests. This change addresses missing documentation on one struct in fuser (which was introduced by our change in awslabs#1098). This change is a good candidate to be contributed to upstream.
