Code Issues Proposed changes

synchronize file update in sysinv agent 

This modification adds a synchronization decorator to the
file update function of the sysinv agent.
This will ensure that the operation does not happen
concurrently with the 'runtime manifest apply' or the
'agent audit' function.
Otherwise, a race condition may happen and cause
manifest corruption or failure to properly handle alarms.

Closes-Bug: #1791969
