Removed the performDeployment boolean in WebLogicJMXCLient since it's
not clear why there should be an option to NOT do deployments.
WebLogic 12.1 container is using the mixed Deployer/JMX strategy, while
12.1.2 is using the full JMX one. Added methods to the JMXClient called
verify*, so that it's clear they do verification only. Renamed
*Containers in the jmx package to make it extra clear they use the full
JMX strategy.
