[STORM-3131] Support hostname-substitution for blobstore.hdfs.principal
https://issues.apache.org/jira/browse/STORM-3131
With this feature, we can set
```
blobstore.hdfs.principal: <headless-user>/HOSTNAME@domain
```
on nodes(nimbi, supervisors) the `HOSTNAME` will be replaced with the
actual hostname on that host.
