[WIP] Create a shared plan for shared Keycloak services

[dimitraz]

• [x] update tests (should use default plan)
• [x] not having _apb_provision_creds or asb_encode_binding generated secrets causes the ansible service broker to crash

@dimitraz jenkins job can't gather logs from apb-test pod, because it fails a few seconds after it starts. I fetched the logs manually:

Does this test pass locally?

Update Sorry, I noticed later that this PR is still WIP, my question is probably irrelevant.
