Vendor middleware_automation.keycloak collection

Needed for keycloak_authentication_v2, to manage Keycloak
authentication flows (e.g. the CCCHH browser flow) as YAML.
Chosen over community.general's own copy of the module (deprecated in
favor of this collection, and limited to 4 sub-flow levels there vs.
10 here).
