Use the new remote-store options

[pruivo]

Depends on

• Introduce new CLI config options for Infinispan remote store keycloak#26756

Relates to:

• Use new remote-store options in HA guides keycloak#27508

I also changed the provision/rosa-cross-dc/Taskfile.yaml to deploy Keycloak in parallel in both ROSA clusters.

Custom Keycloak image available here: quay.io/pruivo/keycloak:gh-25676
Contains keycloak/keycloak#26756 + infinispan/infinispan#11942 (kind of)

We probably can't merge this until this:

keycloak-benchmark/provision/minikube/keycloak/config/kcb-infinispan-cache-remote-store-config.xml

Lines 56 to 58 in 867dbd8

	<!-- This is a workaround for the following issue https://github.com/keycloak/keycloak/issues/27117 and should be removed when the issue is fixed -->
	<write-behind modification-queue-size="1024"/>
	<!-- End of the workaround -->

is needed

I know ... and we wouldn't merge this before KC24 is release as we would also need to update the documentation at the same time?

I was planning to create a PR to add this to the Java code that it adds the workaround as well. But not today, only tomorrow.

This should be ready for review as well.

Tested with openshift / minikube / rosss cross dc setup, smoke tests work. Thanks!
