Added state tabs to issue boards
What does this MR do?
Adds state tabs to the issue boards to match issues & merge requests.
To keep with how the rest of issue boards works - this is done without loading the page & is instead done by simply changing the state value in the store which then automatically sends the request for each list.
This does not add the new issue button like the design - this will be done in a different MR.
