Moved the server_groups to the new API.

As of compute microversion >= 2.21, support for list and show of server
events for deleted servers was added. This however wasn't working using
the openstackclient because the compute GET /servers/{server_id} will
not return a deleted server, so osc_lib.utils.find_resource() fails to
find the server and the command bails early.

This adds a check for a uuid-like <server> arg and uses it directly if
the <server> cannot be found via find_resource().

A note is also added to the command help to indicate that list and show
for deleted servers will only work if a server ID is passed (name will
not work).

We're seeing failures in a recently added tests,
'ServerTests.test_server_add_remove_volume' from
'openstackclient/tests/functional/compute/v2/test_server.py'. These
failures are likely the result of slow CI nodes, but we don't have
enough information in the CI logs to debug them. Starting logging the
various commands executed in tests so that we can see these logs if and
when tests fail.

The old novaclient.v2.server.Server.interface_attach() method is
replaced with proxy.create_server_interface().
In swargs, 'net_id' and 'port_id' are mutual-exclusive, if one of
them is given with value, the other one cannot be None, as the
API would responde with 400 (None is not string).
In unit test, temporary method 'setup_sdk_servers_mock' is added,
because other tests are still using the old 'setup_servers_mock'.
Functional tests are added. Releasenote is generated.

This mostly reuses the existing tests for '--block-device-mapping',
which can hopefully be removed at some point in the future.

This highlights two issues with the implementation of this option.
Firstly, the 'boot_index' parameter is not required so don't mandate it.
Secondly, and more significantly, we were defaulting the destination
type for the 'image' source type to 'local'. Nova only allows you to
attach a single image to local mapping [1], which means this default
would only make sense if you were expecting users to use the
'--block-device' option exclusively and omit the '--image' option. This
is the *less common* case so this is a bad default. Default instead to a
destination type of 'volume' like everything else, and require users
specifying '--block-device' alone to pass 'destination_type=local'
explicitly.

Make use of 'FormattableColumn'-derived formatters, which provide better
output than what we were using before, particularly for the YAML output
format.

Make use of 'FormattableColumn'-derived formatters, which provide better
output than what we were using before, particularly for the YAML output
format. For example, compare before for the 'server show' command:

  $ openstack --os-compute-api-version 2.79 server show test-server -f yaml
  ...
  addresses: private=fdff:77e3:9bb4:0:f816:3eff:fe6d:a944, 10.0.0.44
  flavor: disk='1', ephemeral='0', extra_specs.hw_rng:allowed='True', original_name='m1.tiny',
    ram='512', swap='0', vcpus='1'
  ...

To after:

  $ openstack --os-compute-api-version 2.79 server show test-server -f yaml
  ...
  addresses:
    private:
    - fdff:77e3:9bb4:0:f816:3eff:fe6d:a944
    - 10.0.0.44
  flavor:
    disk: 1
    ephemeral: 0
    extra_specs:
      hw_rng:allowed: 'True'
    original_name: m1.tiny
    ram: 512
    swap: 0
    vcpus: 1
  ...

Similarly, compare before for 'server list':

  $ openstack --os-compute-api-version 2.79 server list -f yaml
  - ...
    Networks: private=fdff:77e3:9bb4:0:f816:3eff:fe6d:a944, 10.0.0.44
    Power State: Running
    Properties: ''
    ...

To after:

  $ openstack --os-compute-api-version 2.79 server list -f yaml
  - ...
    Networks:
      private:
      - fdff:77e3:9bb4:0:f816:3eff:fe6d:a944
      - 10.0.0.44
    Power State: 1
    Properties: {}
    ...

We also fix the human-readable output for the 'tags' field.

Before:

  $ openstack --os-compute-api-version 2.79 server list
  ...
  | tags   | ['bar', 'foo']  |

After:

  $ openstack --os-compute-api-version 2.79 server list
  ...
  | tags   | bar, foo  |
