println leftovers.

The API returns errors with an HTTP code 400, 404 or 500 depending on
the cause with a json object that contains the failure reason. The
error message should be populate to the JMX calling client, translated
to the appropriate exception.
This patch adds the ability to detect API failure and throw a runtime
exception with the returned message.
It is up to the calling method what to do with the exception, if it
would do nothing, the calling client would get a RuntimeException,
depends on origin MBean definition, the caller can catch the exception
and throw a specific kind.
Note that any exception that is thrown must be known to the JMX client
or it will not be able to process it.
As a first step, this patch replaces the jersey client to the newer
version under glassfish, which has an easy way of getting a Reply
object, and check its status before returning the results.
The only difference in the method that uses the APIClient is the use of
MultivaluedHashMap.
The following MBean implementation where changed
ColumnFamily
CompactionManager
Gossiper
EndpointSnitchInfo
CacheService
StorageProxy

In origin an undocumented feature (bug?) is that passing null as a host
name for getRack and getDatacenter returns the rack or datacenter
according to the loopbck address.
This follow the same behaviour, so when the host is null, the function
will not fail but will call the API with the local loopback address

This was a code that was modified from Origin, in the JMX API
initilization is done in the custructor, which mean that it would enter
an endless loop.
When initiliation in the constructor this should be used.
