[Architecture] Move OLM to PMM

Description

We have a successful PoC for OLM done in . However, the code is located in the dbaas-controller.

Since OLM will manage the operator's lifecycle the best place for it is PMM. PMM should install OLM, install operators and run monitoring 

Suggested solution 

  1. Create a package for OLM in `managed/services/dbaas/olm`

  2. integrate with the `managed/services/management/dbaas`

  3. Add unit tests

  4. Move everything related to OLM from dbaas-controller and dbaas-api to PMM

Acceptance criteria 

  1. Integration tests are passing

  2. The end user does not see any difference 

 

Out of scope

1. OLM Catalog

How to test

  1. Start PMM server using the FB: https://github.com/Percona-Lab/pmm-submodules/pull/2987

  2. Register a Kubernetes cluster.

  3. OLM and VM, PXC and PSMDB operators should be installed. 
    This can be verified by running kubectl get pods

  1. Start a DB cluster. The DB should appear. Example:

  2. VM API keys must exist

How to document

  There are still problems as you mentioned in the 3 tickets in the previous comment, but the OLM part works correctly.

We still have this https://jira.percona.com/browse/PMM-11338 bug in this FB. decided to remove PSMDB v.12.0, as it was causing this issue. Can you please take a look?
Tested using the latest FB https://github.com/Percona-Lab/pmm-submodules/pull/2997.
