Create epic for tracking known issues

[ulisesh]

@markwilkie: Namely, setup and epic for this and add a PR to the dev handbook

[missymessa]

Is the epic going to track Known Issue like the GitHub project currently does, or is this an epic for future work?

[missymessa]

Let's use a label instead, so action item is just to create the label (and this is only for infra Known Issues).

And add documentation for this :D

Can reopen this work if we need it in the future.
