epriestley c21a71f024 Cache generation of the SSH authentication keyfile for sshd
Summary:
Ref T11469. This isn't directly related, but has been on my radar for a while: building SSH keyfiles (particular for installs with a lot of keys, like ours) can be fairly slow.

At least one cluster instance is making multiple clone requests per second. While that should probably be rate limited separately, caching this should mitigate the impact of these requests.

This is pretty straightforward to cache since it's exactly the same every time, and only changes when users modify SSH keys (which is rare).

Test Plan:
  - Ran `bin/auth-ssh`, saw authfile generate.
  - Ran it again, saw it read from cache.
  - Changed an SSH key.
  - Ran it again, saw it regenerate.
