Cause:
Web ui backend internally uses syntax of a command `pcs constraint colocation add` that is not supported yet.
Consequence:
Adding a colocation constraint from the web ui always fails.
Fix:
Web ui backend has been fixed to use current syntax of command `pcs constraint colocation add`.
Result:
Adding a colocation constraint from the web ui succeeds.
