[autotest] move tests in rpm_controller to a separate file

rpm_controller is getting big.
Move tests in rpm_controller to rpm_integration_test.py
The tests are commented out because most of the ports are in actual
use now.

TEST=Lock some hosts, change rpm_integration_test to point to those
locked hosts and run the tests.
