Description

Currently HAWQ only accepts the principle 'postgres' for kerberos settings.
This is because it is hardcoded in gpcheckhdfs, we should ensure that it can be parameterized.

Also, it's better to change the default principal name postgres to gpadmin. It will avoid the need of changing the the hdfs directory during securing the cluster to postgres and will avoid the need of maintaining postgres user.
