Compute: remove get call for service

[Abhishek Kekane]

Nova has not implemented show service API (GET individual service details). So IMO it make no sense to have this support in openstacksdk. As of now "get_service" from openstacksdk raises ResourceNotFound exception [1].

Error log while getting the service with valid service id:

Traceback (most recent call last):
File "test_openstacksdk_compute.py", line 275, in <module> get_service = conn.compute.get_service(5)
File "/opt/stack/python-openstacksdk/openstack/compute/v2/_proxy.py", line 1078, in get_service return self._get(_service.Service, service)
File "/opt/stack/python-openstacksdk/openstack/proxy2.py", line 37, in check return method(self, expected, actual, *args, **kwargs)
File "/opt/stack/python-openstacksdk/openstack/proxy2.py", line 225, in _get http_status=e.http_status, cause=e.cause)
openstack.exceptions.ResourceNotFound: ResourceNotFound: No Service found for 5, The resource could not be found.

    Remove get_service method from compute

    If a get_service method is called with a valid service id,
    then it raises ResourceNotFound exception as this API is not
    implemented in nova.

    Removed this method and related test cases to cleanup the code.
