Removing redundant validation for rebuild request.

Any method decorated with wsgi.action will need to have
the said key, in this case 'rebuild', before it
reaches the relevant code block. If not, a key
error is raised when the wsgi.action code kicks in. This
code is at openstack/wsgi.py in the  _process_stack
method and subsequently the self.get_method method.
A KeyError is raised and caught. Removing the redundant
check for rebuild api.
