users: create cache for user lookups (#16100)
* users: create cache for user lookups

This PR introduces a global cache for OS user lookups. This should
relieve pressure on the OS domain/directory lookups, which would be
queried more now that Task API exists.

Hits are cached for 1 hour, and misses are cached for 1 minute. These
values are fairly arbitrary - we can tweak them if there is any reason to.

Closes #16010
