      Description (describe the discontinued feature): Following pacemaker 3, pcs no longer supports location constraints with multiple top-level rules. Only one rule per constraint is allowed.

      Consequence (describe the recommended replacement, if applicable):
      Commands 'pcs constraint rule add | delete | remove' have been removed. If users have constraints with multiple rules, they should run "pcs cluster cib-upgrade" to update to the latest cib schema. During the update, pacemaker creates a constraint for each rule, so that there will be only one rule in each constraint.

      Goal

      Pacemaker team has announced upstream that support for multiple rules in a location constraint is going to be dropped in Pacemaker 3. Pcs needs to follow that.

      Acceptance criteria

      • commands 'pcs constraint rule add', 'pcs constraint rule delete | remove' don't update cib, they print a message explaining the commands have been removed
      • usage and man page no longer describe the commands
      • the change is described in man pages in 'changes in pcs-0.12 section'
      • capabilities are updated
      • changelog is updated
      • exporting constraints with multiple rules as commands no longer uses 'pcs constraint rule add', it creates a new constraint for each rule
