Ability to merge tags

When you allow your agents to create tags, you’ll sooner or later end up with duplicate tags e.g. due to typos.

It would be useful here if admins had the ability to merge tags. E.g. if the list would show these tags:

  • some_tag - 10 tickets
  • smoe_tag - 1 ticket

where smoe_tag is obviously a typo of some_tag, I would like to have a merge button for smoe_tag that, when clicked, prompts me for the new tag. I would then choose the some_tag tag from a list, and Zammad would then remove the tag smoe_tag from all affected tickets, re-tag them as some_tag, and then delete the old smoe_tag tag.
