The reboot_server helper method that was added to tempest [1] was part
of tempset tag 28.1.0. Downstream 16.2 limits git installation to
28.0.0 and no longer supports clone from master. Taking logic from [1]
for reboot_server and applying it to the base whitbox test class
since there are two tests that currently leverage the method.
