1. Proposed title of this feature request

Add annotation to operators supported in disconnected environments

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

There is a list of operators supported in disconnected mode in KCS 4740011 [1], but that information is not shown for all operators in the OpenShift web console.
Operators like ServiceMesh show that it works in disconnected environments, but others like Jaeger, Pipelines, Gitops and Elasticsearch don't.

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

To have the information when trying to install the operator, and not in a different document [1].

4. List any affected packages or components.

As shown in the step 5 of the blog post in [2], there is an annotation to announce to the OperatorHub that the Operator runs in disconnected environments, so looks like each operator is responsible of that information (confirmed by [3]):
