Description

Users are used to modifying cassandra via yaml and JMX (for dynamic configs) but accord does not integrate with this right now; we should enhance Accord to expose configs that are defined in cassandra yaml.

As an extension on this, we should figure out which configs are “dynamic” and allow overriding via JMX or system vtable.
