Description
Add the ability to generate a dashboard for a custom metric. This should be optional, ie. a user can define a metric without generating a dashboard for it.
We should be able to reuse most of our dashboard generation code.
Note: the PR includes examples of usage. Cf for instance https://github.com/netobserv/network-observability-operator/pull/609/files#diff-0a32cdb0b9df09ffa650e4fb007b64589488e36d94b0872a98de92edaed1821e
