Use _HOST instead of FDQN when configuring principal for IgfsSecondaryFileSystem with kerberos enable

[C Reid]

Hi Igniters,​​

I file an issue about providing a more friendly way to configure kerberos principal for kerberized hdfs. And i'm glad to work on it, because it is an easy one.

More details can be found:
https://issues.apache.org/jira/browse/IGNITE-6747

Suggestions are welcomed.

Thanks and regards,

Reid
