* api: return 404 for alloc FS list/stat endpoints
If the alloc filesystem doesn't have a file requested by the List
Files or Stat File API, we currently return a HTTP 500 error with the
expected "file not found" error message. Return a HTTP 404 error
instead.
* update FS Handler
Previously the FS handler would interpret a 500 status as a 404
in the adapter layer by checking if the response body contained
the text or is the response status
was 500 and then throw an error code for 404.

go-getter 1.5.9 includes a patch in 1.5.6 that automatically unpacks
uncompressed tar archives. Previously Nomad only unpacked compressed
archives, but documented that it unpacked all archives.

As we have continued to see reports of #9506 we need to elevate this log
line as it is the only way to detect when plans are being *erroneously*
rejected.
Users who see this log line repeatedly should drain and restart the node
in the log line. This seems to workaorund the issue.
Please post any details on #9506!
Log the failure error when the agent fails to start. Previously, the
agent startup failure error would be emitted to the command UI but not
logged. So it doesn't get emitted to syslog or `log_file` if they are
set, and it makes debugging much harder. Also, logging the error again
before exit makes the error more visible: previously, the operator
needed to scroll to the top to find the error.
On a sample failure, the output will look like:
```
==> WARNING: Bootstrap mode enabled! Potentially unsafe operation.
==> Loaded configuration from sample-configs/config-bad
==> Starting Nomad agent...
==> Error starting agent: setting up server node ID failed: mkdir /path-without-permission: read-only file system

```
This change adds the final `ERROR` message. It's easy to miss the `==>
Error starting agent` above.
The system scheduler should leave allocs on draining nodes as-is, but
stop node stop allocs on nodes that are no longer part of the job
datacenters.
Previously, the scheduler did not make the distinction and left system
job allocs intact if they are already running.
I've added a failing test first, which you can see in https://app.circleci.com/jobs/github/hashicorp/nomad/179661 .
Fixes https://github.com/hashicorp/nomad/issues/11373
Pick up https://github.com/golang/snappy/pull/56 to handle arm64 architectures to fix panics. tldr; Golang 1.16 changed `memmove` implementation for arm64 requiring additional cpu registers that snappy wasn't preserving in its assembly implementation.
Other projects have experienced this issue as well, searching for `encode_arm64.s:666` on your favorite search engine will reveal some. Vault updated the dependency earlier this August: https://github.com/hashicorp/vault/pull/12371 .
I believe this issue affects Nomad 1.2.x and 1.1.x. Nomad 1.0.x use Golang 1.15 and isn't affected. However, backporting the change to 1.0.x should be harmless.
Fixed https://github.com/hashicorp/nomad/issues/11385 .
