fix(keepalived): create deployment namespace

[Tadas Sutkaitis (fitbeard)]

What changed

• create the openstack namespace before deploying Keepalived resources;
• preserve the existing keepalived_enabled guard;
• add a release note.

Why

The role assumed another role had already created its namespace. Running Keepalived in a focused or reordered deployment therefore failed even though all of its other inputs were present.

This production fix is extracted from #4152 so it can be reviewed, released, and backported independently from selective CI.

Validation

• file-scoped pre-commit hooks passed;
• git diff --check passed;
• the repository-wide Ansible lint traversal reached all roles and only failed on the existing galaxy[no-changelog] metadata issue;
• Reno parsed the new note and only reported the repository's existing duplicate release-note UID.

Remove the literal newline escape from the release note

The block scalar preserves \n as two literal characters, so the generated changelog will display “enabled\n before” instead of a normal sentence. Replace the escape with an actual line break so the published release note remains natural English.
