Provide multiple server offerings

In order to reduce the memory footprint of Infinispan in server mode, we need to remove as many of the unnecessary dependencies from the server as possible. Some use-cases require more functionality than others, therefore our intention is to provide the server in two flavours:

1. A "lean" server, that exposes all management operations over JMX and is based on jboss-modules
2. A server based upon widlfly-core, which provides users with standalone/domain modes that they're currently accustomed to as well as DMR operations via the CLI.

This JIRA is simply a parent issues to keep track of all the sub-tasks required.
