AMQP-378 Support Bulk Queue Changes

JIRA: https://jira.springsource.org/browse/AMQP-378

Consumers are restarted when queue changes are made.

Currently only one queue can be added/removed at a time.

Change the method args to varargs and make the method names
plural.

Deprecate the singular methods - we have at least one user
using this feature from the snapshot. The deprecated methods
can be removed in 1.3 GA.
