Upgrades: fix up the rabbitmq HA mode like in new ocata deployments
In ocata we changed the rabbitmq ha policy to "ha-exactly" via the
following changes:
- tht: Iace6daf27a76cb8ef1050ada0de7ff1f530916c6
- puppet-tripleo: Ib62001c03e1e08f58cf0c6e0ba07a8879a584084
We took care of the upgrade path via I3a97505d2ae1ae27f3080ffe74c33fdabffd2420
With the move to the ansible-based composable upgrades we left this change out.
And now an upgraded environment has the following policy:
- Upgraded environment
Attributes: set_policy="ha-all ^(?!amq\.).* {"ha-mode":"all"}"
- New environment
Attributes: set_policy="ha-all ^(?!amq\.).* {"ha-mode":"exactly","ha-params":2}"
We need to add this pcs resource change to the our upgrade scripts.
