20661 - Util#versioncmp fails in some cases

The versioncmp helper failed to correctly compare 1.2.10 and 1.2.8
but this has already been fixed in Puppet where we got our logic
from first so we're just grabbing whats in Puppet now to resolve
this
15182 - Support Stomp 1.1 in the RabbitMQ and ActiveMQ plugins

This adds Stomp 1.1 support for the ActiveMQ connector by adding
the following config options:

    plugin.activemq.heartbeat_interval = 30
    plugin.activemq.stomp_1_0_fallback = true
    plugin.activemq.vhost = mcollective

which allows users to set heartbeat intervals, custom vhosts and the
ability to enforce a connection should only be accepted when stomp
1.1 can be used
