properties config - allow validation and reporting of misconfiguration

the properties applied via ARTEMIS-3627 get ignored if they are not correct.

There is currently no validation.

It would be great if there was an additional property that would control that...

validate=error|log|ignore

in the log case, in addition to log.info(...), having a jmx view of the map key/values that got ignored would be great.

in the error case, I guess there is still log.error but the broker won't start, it will error out.

This will need a rework of beanutil b/c it currently does not support feedback based on missing fields, it will happily ignore.
