JBQA-8764: test for DatabaseLoginModule which uses replaceable datasource
[WFLY-3029] add remove-jndi operation for JMS resources

* add remove-jndi operation to jms-queue, jms-topic and
  connection-factory resources
* refactor the code to mutualize handlers for add-jndi and remove-jndi
  operations
* add rollback handler for these operations
* change jms-queue entries attribute to read-write. There is no
  reason this attribute can not be written (although the runtime
  will need to be reloaded to take it into account)
* bump up management version to 2.1.0

[WFLY-3094] Validate address-settings configuration

* check that if address-settings' expiry-address and dead-letter-address
  are defined, then there must be corresponding resources (either
  jms-queue, jms-topic, or core-queue) bound to them.
  If that's not the case, logs a warning that there me be unintended
  message loss.
* add 2 JMS Queue (ExpiryQueue and DLQ) to the full configuration to
  satistfy these constraints.
