openstack-test: migrate CI config to OTE (openshift-tests-extension)

Update the openstack-test main CI configuration to support the OTE
migration in openshift/openstack-test#260.

Changes:
- binary_build_commands: build OTE extension binary via 'make
  tests-ext-build', package as tar.gz, and place at /usr/bin/ for
  payload discovery by openshift-tests
- build test: verify the extension binary with --help instead of the
  removed openstack-tests binary
- test/ccpmso jobs: use new openstack-test-openstack-ote step ref
- dualstack jobs: override test phase with openshift-e2e-test +
  openstack-test-openstack-ote (replacing the old chain that used
  openstack-test-openstack)

New step registry ref openstack-test-openstack-ote:
- Runs from 'tests' image (openshift-tests) instead of 'openstack-tests'
- Discovers the openstack-test extension from the release payload
- Grants image-puller access for extension discovery
- Supports same env vars: OS_CLOUD, OPENSTACK_TEST_SKIPS, CONFIG_TYPE
- Runs 'openshift-tests run openstack-test/all' suite

The old openstack-test-openstack step ref is preserved for older release
branches that still use the standalone openstack-tests binary.
