Updates to the Infinispan chapter of the EAP Configuration Guide

Documentation updates and other changes are required to the Infinispan section of the EAP configuration guide.

The preferred approach to handling this Jira is to remove content from the EAP documentation set and hand over to RHDG with the goal to reduce maintenance overhead for the EAP documentation team and eliminate duplicate/redundant content that could result in issues for Red Hat customers.

Completion of this Jira issue depends on a technical decision for how users should configure Data Grid integration for remote caches or embedded caches. There are two scenarios:

Users can create and configure embedded and remote caches with the Infinispan subsystem. This is an EAP specific implementation that requires documentation for the management CLI commands. However all Data Grid specific configuration detail, including descriptions of cache modes (distributed, replicated, local) should be sourced from the DG doc set.

Users can add DG dependencies for embedded and remote caches to their projects. In this case EAP documentation can simply re-use assemblies and modules from the DG doc set.
