Add configurable properties for each configuration lookup class

See ISPN-379.
Currently, most pluggable components can only be specified by a lookup class name. While some accept a configurable Properties object (e.g. JGroupsChannelLookup), not all do (e.g. MBeanServerLookup). Consequently, it is very awkward to implement a parameterized MBeanServerLookup implementation (e.g. to find the server using a jmx agent id, use an injected mbean server instance, etc.).
I can think of 2 ways to improve this:
1. Add the ability to specify properties objects for each pluggable component. e.g. GlobalConfiguration.setMBeanServerProperties(...), MBeanServerLookup.getMBeanServer(Properties properties)
2. Allow the user to define the instance directly. e.g. GlobalConfiguration.setMBeanServerLookup(MBeanServerLookup lookup)

Ideally, Infinispan could support both mechanisms. The 1st allows flexible declarative configuration. The 2nd allows even more flexible programmatic configuration.

Thinking this through a bit more - we can support both approaches using the following (using MBeanServerLookup as an example):

• Leave MBeanServerLookup interface as is
• Replace GlobalConfiguration.setMBeanServerLookup(String) with GlobalConfiguration.setMBeanServerLookup(MBeanServerLookup lookup)
• Create generic implementation of MBeanServerLookup that delegates to an instance constructed via class name and java bean properties
• If lookup class is specified in the xml, construct generic MBeanServerLookup object accordingly (using class name + properties)

Just a thought. Approach #1 is good enough.
