### What changes were proposed in this pull request?
We have various points in the hive codebase that communicate with zookeeper
service.
Apache Hive JDBC Driver fetches the HS2 URLs for service discovery.
Hive Server2 uses ZK to register itself for service discovery, table
locking, ZK TokenStore etc.
Hive Metastore also uses ZK to register itself for service discovery, ZK
Tokenstore
If Zookeeper is TLS enabled with a different keystore/truststore type, we
need to be able to specify this type when establishing this connection.
Otherwise, it defaults to JKS which may not be the case all the time.
### Why are the changes needed?
To be able to support service discovery (and other features) that use
zookeeper in hive, we have to allow for a keystore/truststore type to be
specified in the config.
### Does this PR introduce _any_ user-facing change?
No, its backward compatible. But only in cases where non-JKS storetypes are
used, we will need additional configuration either in the JDBC URL or in the
hive-site.xml for HS2/HMS services.
### Is the change a dependency upgrade?
No
### How was this patch tested?
UTs
