Bugs: AMBARI-15127
    https://issues.apache.org/jira/browse/AMBARI-15127


Repository: ambari


Description
-------

Need to apply multiple retries for Ranger DB setup calls to handle concurrent calls to one
DB from 2 different hosts where Ranger Admin is installed.
This scenario is needed to handle upgrades of HDP in a case when Ranger HA is enabled.
