This patch address two issues with column family removal: 1. Use a safe iterator when removing from a hash 2. Explicitly unregsiter the MBean instead of waiting for the server to do it, to prevent using MBean that does not have an actual Column Family.

Urchin JMX Interface
This is the JMX interface for Scylla
Compile
To compile do:
mvn install
Run
The maven will create an uber-jar with all dependency under the target directory. You should run it with the remote jmx enable so the nodetool will be able to connect to it.
java -Dcom.sun.management.jmxremote -Dcom.sun.management.jmxremote.port=7199 -Dcom.sun.management.jmxremote.local.only=false -Dcom.sun.management.jmxremote.authenticate=false -Dcom.sun.management.jmxremote.ssl=false -jar target/scylla-jmx-1.0.jar
Setting IP and Port
By default the the JMX would connect to a node on the localhost on port 10000.
The jmx API uses the system properties to set the IP address and Port. To change the ip address use the apiaddress property (e.g. -Dapiaddress=1.1.1.1) To change the port use the apiport (e.g. -Dapiport=10001)
