With compute API microversion 2.53, nova-compute services
can only be deleted with the ID as a UUID to uniquely identify
the service in a multi-cell deployment. This documents that for
the "compute service delete <service>" argument. The description
of the "compute service list" command is also updated to mention
that the ID can be retrieved as a UUID using 2.53 or greater.

With compute API microversion 2.53 there is a single
PUT /os-services/{service_id} API which takes the service
id as a UUID. Since the openstack compute service set
command only takes --host and --service (binary) to identify
the service, this change checks if 2.53 or greater is being
used and if so, looks up the service by host and binary and
calls the appropriate methods in novaclient.

If the command cannot uniquely identify a compute service
with the given host and binary, an error is raised. A future
change could add an --id option to be used with 2.53+ to
pass the service id (as UUID) directly to avoid the host/binary
filtering.

When the --name-lookup-one-by-one option passed to the 'server list'
command, the image and flavor names will be looked up for each
server being listed instead of fetching all image/flavor names.

The current code assumes all servers have an image attribute, but
servers booted from volumes have no image, so the following error is
raised when listing BFV servers with --name-lookup-one-by-one:

  AttributeError: ('unicode'|'str') object has no attribute 'get'

The error occurs when the code attempts server.image.get('id').

This fixes the --name-lookup-one-by-one code not to assume an image
for a server. The unit tests for 'server list' have also been
robustified to feature one BFV server to enhance our test coverage.

There is a typo in the endpoint group deletion, due to this you
can't remove endpoint groups once assigned. I am adding also the
unit tests to avoid this kind of issues in the future

If a required service is not enabled then we skip the test.
The discovery is done by tests/functional/base.py:is_service_enabled
but this method is broken, credentials are not passed to the
'openstack service show' command so every call will fail and every test
that relies on it will be skipped. This commit fixed that method and
the issues that popped up when re-enabling tests.

Network segment range:
 - issue where we assumed network-segment-range extension is always
   present
 - issue where we compare integers and string representations of numbers

Subnet:
 - issue where we try to deepcopy an uncopyable object in UnsetSubnet

"project_id" attribute should not be set to None on shared network
segment range creation since it is not a valid string type which is
required for the API.
