[Feature Request] Add deletion of workflow execiutions document from UI

[azgaviperr]

After some time of running instance or in large organisation, the DB is getting really heavy.

It does need a solution to purge it with condition from the UI (working currently to do it by opensearch query).

For Exemple: older than, Status failed etc.

I think it needs a schedule you can set up that cleans it up for you. Let's start with a Workflow talking to Opensearch and figure out how it should work ;)

Make sure to release it!!
