Proposed title of this feature request

Allow annotations to be added to namespace/project that OLM creates when installing operators

What is the nature and description of the request?

This is related to a requirement of the OpenShift Compliance Operator that requires certain pods to run only on master nodes. Although this can be achieved by setting `nodeSelector` to master nodes, it fails in edge case scenarios where user has explicitly set the `schedulers` `defaultNodeSelector` to say worker. See Bugzilla  1947248 . 

To address this, the project should be annotated with  `openshift.io/node-selector: “”` which can only be done by OLM at the time the operator is installed or by user manually as a workaround after the operator is installed and fails to come online. 

So the RFE is to allow operators to specify in their CSV or elsewhere, annotations that should be applied to the namespace/project. 

Why does the customer need this? (List the business requirements here)

This feature is needed by certain operators that require projects/namespaces to be created with certain annotations already set for the operators to run
