Description of problem:
Currently the API has support for passing session id as a parameter but username and password are still required.
We would like to have the ability of accessing the API without needing to input username and password when we are passing the session id.

Version-Release number of selected component (if applicable):
rhevm-sdk-java-3.6.2.0-2.el6ev.noarch.rpm

How reproducible:
100%

Steps to Reproduce:
1. Try to access API using only session ID

Actual results:
Username and password are required

Expected results:
We can access the API only passing session id to the constructor.
