Description

The durable user sessions developed in #28265 should work together with #28745.

Acceptance criteria (draft):

• If persistent user sessions and external Infinispan are enabled, the user sessions should be handled by the the persistent user sessions code.
• If external Infinispan is enabled, the persistent user sessions shouldn't use the external Infinispan for caching sessions.

Motivation

Be able to provide an A/A Multi-site persistent session w/ external Infinispan.

Acceptance criteria

• Implement a switch to disable caching in single-site setup to allow for performance comparison
• Do not use any caches for user sessions in a multi-site setup as they can't be kept up-to-date in a A/A setup
• Performance test in KCB should show no regression
• Functional test in KCB green: A/P remote cache -> A/A remote cache + persistent sessions (waiting for Pedro's PR)
