HBaseDelegationTokenProvider (Flink : Runtime 2.1.0 API)

java.lang.Object
- org.apache.flink.runtime.security.token.hadoop.HBaseDelegationTokenProvider

All Implemented Interfaces:

org.apache.flink.core.security.token.DelegationTokenProvider
```
@Internal
public class HBaseDelegationTokenProvider
extends Object
implements org.apache.flink.core.security.token.DelegationTokenProvider
```
Delegation token provider implementation for HBase. Basically it would be good to move this to flink-connector-hbase-base but HBase connection can be made without the connector. All in all I tend to move this but that would be a breaking change.
