Expose Fuse Version and Patch Level

There is currently no reliable way to determine which version of Fuse is installed without correlating a bundle version like 630310 to a patch.

Options:

1)
osgi:version prints a version in a way we represent it:
Red Hat JBoss Fuse 6.3 R5

2)
http://<url>:8181/hawtio/jolokia/version

Only shows the activemq version for some reason. adding in the version and patch level would work

{"request":

{"type":"version"}

,"value":{"agent":"1.3.6","protocol":"7.2","config":

{"agentId":"10.10.183.203-14147-1e01d9a1-servlet","agentType":"servlet","allowErrorDetails":"false","includeStackTrace":"false","mbeanQualifier":"qualifier=hawtio"}

,"info":{"product":"activemq","vendor":"Apache","version":"5.11.0.redhat-630310"}},"timestamp":1515697368,"status":200}

3) JMX MBean to easily query version

4) Provide a version.txt per:
