to false.
[TORQUE-860] Allow to deploy Message Processors and Jobs stopped

Allows to deploy message processors and jobs stopped. This feature will
make it possible to start jobs and message processors but not to run
them at application boot time.

Three new methods were exposed for message processor management: start,
stop and started?.

This commit includes integration tests.
