The purpose of this feature is to allow Phase 3 of decomposition rollout
as described in https://gitlab.com/groups/gitlab-org/-/epics/6160#progress.

The idea is that we configure a separate DB (CI) with replicas, but due
to transaction visibility we need to share primary connection to `main`
database.

This adds a temporary feature enabled via `FF` to allow this type
of behavior change.

Before this change we would store `model` for the purpose of understanding
sticking context for a object. This changes to prefer `sticking` which
is directly connected to `LB` context on which the `sticking` is evaluated.

This is in preparation to allow asynchronous handling of replicas
and re-use of primary connection in a load balancing context.

This uses the same actions component so that when

This also mounts the Action Cable engine all the time.
Mounting the engine has minimal impact on memory so we should just mount
it all the time to reduce configuration complexity.
