There were a number of 'get_osc_show_columns_for_sdk_resource' defined
in-tree. However, osc-lib has provided this method for some time (since
2.2.0, June 2020 [1] - our minimum version is currently 2.3.0) so
there's no need to provide our own copies. Remove them.

We use singular form for delete command argument in all places.
This commit replaces conntrack-helper-ids with a singular form.
The only visible change is a fix for the help message below.

  openstack network l3 conntrack helper delete
      <router>
      <conntrack-helper-ids>
      [<conntrack-helper-ids> ...]

Neutron has got CRUD API for L3 conntrack helper since some time.
This patch adds support for it in the OSC.
OpenStack SDK supports that since [1]

This patch also bumps minimum OpenStack SDK version to
the 0.56.0 as that version introduced support for the
Neutron's L3 conntrack helper.

To deprecate and drop support for neutronclient CLI and use only
OSC we need feature parity between OSC and neutronclient.
Last missing piece here is possibility to send in POST/PUT requests
unknown parameters to the Neutron server.
This patch adds such possibility to the OSC.

assertItemsEqual was removed from Python's unittest.TestCase in
Python 3.3 [1][2]. We have been able to use them since then, because
testtools required unittest2, which still included it. With testtools
removing Python 2.7 support [3][4], we will lose support for
assertItemsEqual, so we should switch to use assertCountEqual.

The neutron API supports filtering ports by name, but
the CLI was missing support for it like it does for
other networking resources.
