The app can be installed by any administrator on the workspace, but currently there's no fail switch to abort the installation if any other administrator has installed ucx. Problems are mainly related to:

• different installations using the same inventory database, overriding the state without any coordination. Edge case is related to one administrator dropping a database, which breaks the workflows of other installations
• starting other workspace-state-changing workflows, like group migration

To prevent this:

• every time a task is run, check configurations of every other potential installations and fail the run if database with the same name detected
• on installation, detect all of the other configurations and fail if the same database found
• technically, we can also add a check for database not to exist at the installation step, but it'll delay on the start of the warehouse.
