Devs:
We need to verify these actions works for the following:
1. Workbench
2. Pipeline
3. Codeflare-sdk 

QA:

1. Platform team QA co-ordinator (Matthew Mahoney or Adrián Sanz Gomiz) (requires change install_config.yaml)
2. Functioning for notebook should work with these new certs.
3. Executing pipeline from notebook should work with these new certs.

Docs:

1. Check with Platform team if there is overall effort.
