To reduce the time it takes to audit subclouds by certmon, the
number of subclouds that can be audited in parallel was increased
from 4 to 20 and the timeout to check if it's possible to establish
a connection was reduced from 10 to 5.
Test plan:
- PASS: Lock/unlock a system controller with these changes and
verify the config file was correctly updated and certmon is
auditing subclouds successfully
