Review comment:
@bharatviswa504 - latest commit contains changes to ozone.s3g.grpc.port
-> ozone.om.grpc.port in OMConfigKeys. This impacts the
TestOzoneConfigurationFields integration test as key is not in site xml file,
so added line to ignore key.

Review comment:
Removed code to set address if not defined, instead logging error and
throwing `ConfigurationException`.

Review comment:
Renamed fields for data structures used in base class :
omProxiesNodeIdKeyset (as we need to set the node ids which are the keys for
the base class omProxies data structure).

Review comment:
Revised the proxies datastructures needed by the base class,
`OMFailoverProxyProvider`: added comment that we need to set the keyset for
both the underlying `omProxies` and `omProxyInfos` base class data structures
and set both the omProxies and `omProxyInfos` with the `nodeId` for the avail
oms.
```
// set base class omProxies, omProxyInfos, omNodeIDList
// omProxies needed in base class
// omProxies.size == number of om nodes
// omProxies key needs to be valid nodeid
setOmProxies(omProxiesNodeIdKeyset);
// omProxyInfos keyset needed in base class
```
