[COMMON] Fix db-metrics readiness timeout issue
DB connection from Policy Framework components fail intermittently with
Connection refused error. Upon investigation, identified that
mariadb-metrics readiness is failing with timeout, and thereby affecting
the db connectivity intermittently.
So, changing readiness timeout from 1 second to 5 seconds so that
there is enough time to get back the /metrics response
and readiness can pass. Also making the properties configurable.
Similar issue could happen in other components too.
