Remote Naming throws the same exception for different causes

A generic NamingException are thrown if all of the servers specified are unreachable as well as if the user/pass are invalid and a security exception is thrown up, they both are converted into a RuntimeException and a message listing the servers it was unable to call is reported.

We should be throwing a different exception in the cases we know the cause, such as connection timeout or authentication exception.

If all the the servers specified are not not running:
--------------------------------------------------------------------------------------------
javax.naming.NamingException: Failed to connect to any server. Servers tried: [remote://localhost:4447]
at org.jboss.naming.remote.client.HaRemoteNamingStore.failOverSequence(HaRemoteNamingStore.java:213)

If one of the servers is running, but the client's username/password are incorrect
--------------------------------------------------------------------------------------------
javax.naming.NamingException: Failed to connect to any server. Servers tried: [remote://localhost:4447]
at org.jboss.naming.remote.client.HaRemoteNamingStore.failOverSequence(HaRemoteNamingStore.java:213)
