   ### Search before asking
   
   - [X] I have searched in the [issues](https://github.com/apache/incubator-kyuubi/issues?q=is%3Aissue) and found no similar issues.
   
   
   ### Describe the feature
   
   Enhance `HiveDelegationTokenProvider` to renew delegation tokens of multiple Hive metastore clusters.
   
   ### Motivation
   
   Kyuubi supports [setting Hive metastore uris in JDBC connection URL](https://kyuubi.readthedocs.io/en/latest/deployment/hive_metastore.html#via-jdbc-connection-url).
   But current `HiveDelegationTokenProvider` implemented in #1009 can only renew delegation tokens of Hive metastore defined in hive-site.xml.
   
   For users who frequently access different Hive metastore clusters, the Kyuubi engines visiting non default Hive metastore server are still limited by Hive token's expiration time.
   
   
   ### Describe the solution
   
   Introduce a Kyuubi configuration `kyuuib.credentials.hive.metastore.uris` to specify extra Hive metastore URIs.  
   URIs should be specified in format "thrift://host01:port01,thrift://host02:port02;thrift://host11:port11,thrift://host12:port12", where "," separates URIs belonging to same metastore cluster, ";" separates URIs of different metastore clusters.
   
    `HiveDelegationTokenProvider`  will create a `HiveMetaStoreClient` for each Hive metastore URIs and periodically renew the delegation tokens.
   
   ### Additional context
   
   _No response_
   
   ### Are you willing to submit PR?
   
   - [X] Yes I am willing to submit a PR!
