rename activemq-broker feature to a-mq-broker to reflect the fabric dependency (or difference from activemq)

from irc:
bibryam left the chat room. (Ping timeout: 606 seconds)
[11:27am]ch007m: jstrachan: We have 2 problems when we use JBoss Fuse without fabric & ActiveMQ : 1) bundle mq-fabric must be deployed as there a dependency required by feature activemq-broker & 2) activemq.xml file defines as transporconnector tcp://0.0.0.0:0 --> 0.0.0.0:61626
[11:42am]gtully: ch007m: the only real differences between a-mq and activemq is that it is fabric aware, so the pid factory from mq-fabric is 'fabric' aware.
[11:42am]gtully: ch007m: a-mq standalone defines standalone=true in the pid file and defines the openwire.port property to specify 61626. which u can use for 2)
[11:43am]gtully: maybe we need to rename the features - a-mq-broker to denote the fabric requirement different from activemq-broker (from apache)
[11:45am]ch007m: gtully: Make sense. Otherwise end users are confused and don't know which features to be used for project using fabric or non fabric
