jammy support everywhere

[Nobuto Murata]

The landscape deployment still relies on focal. And we should use the latest LTS, jammy, everywhere.

Rev. 23 has focal as the default series and only landscape-server has an override as jammy. haproxy, postgresql, and rabbitmq-server units will be on focal.

Rev. 22 has jammy as the default series but haproxy has an override as focal.

Testing replacing the haproxy and rabbitmq-server revisions in the scalable bundle with revisions that can deploy to jammy.

Looks like some work will be required to make things compatible with the latest rev of haproxy. I've opened LP: #2040331 to resolve this.
