Reword some things
Added wait_for_event function to saltmod

This allows the orchestrate system to watch the event bus for arbitrary
events.
Reduce unnecessary stats in minion cache

Refs #14645

Instead of doing two seperate FS operations to check for the existence
of a file and then open in, simply attempt the file open and continue if
it fails. Should save one stat per operation.

This is a relatively minor optimmization but in cases of a master with
many minions, could have noticeable performance improvements when
iterating over tens of thousands of files.
