Add support for stateful attribute of security groups,
using --stateful and --no-stateful flag on security group.
This allows a user to create security groups with stateful
false.

Add commands to osc to call the two new API methods introduced by
new Neutron extension: extraroute-atomic.

Bump our openstacksdk requirement to >=0.38.0 which contains
the corresponding sdk change.

The lower-constraints of dogpile.cache and keystoneauth1 are bumped
because of requirements bumps in openstacksdk.

The lower-constraint of decorator is bumped because of problem already
fixed by amotoki here: https://review.opendev.org/701706

We seem to be having occasional overlaps in the ranges, as they were
identical in all tests, change each test to not overlap the others
so running in parallel is not racy.

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
