1. Proposed title of this feature request
Support operator-sdk for building bundles and adding metadata to the bundle.

2. What is the nature and description of the request?

operator-sdk is a common tool used for building bundles and installing bundles in our CI.

It is also the only way to generate the metadata for layered operators. If this tool is not supported than layered operators develops need to build their own custom scripts to inject the metadata. This is painful.

https://sdk.operatorframework.io/docs/building-operators/golang/references/markers/

In fact, this is the only way to add metadata to bundle but since operator-sdk is "deprecated", we are left using a deprecated tool or each team is left to build their own script to do this.

4. List any affected packages or components.

All layered operators.
