When a node is part of a cluster but is down (like in the situation where
a cluster is taken down and up again but not all nodes are up). There is
no application_state information for that node.
This patch check that the information exists before using it to prevent
null pointer exception.
After this patch, a call to nodetool gossipinfo would return the
available information without failing.

This patch change getAllEndpointStates implementation. The proxy now
gets from the API a list of objects, it creates the endpoint map from it
and create the result string.
After this patch the nodetool gossipinfo should be formatted like
origin.
After this patch the nodetool gossipinfo return:

This adds the FailureDetectorMBean and its implementation.
Setting the phi is not supported yet and will be added when the code
will be completed inside the failure_detector implementation.
