XD-1550 Propagate BeanFactory to Hand-Built Beans

JIRA: https://jira.spring.io/browse/XD-1550

SI Components need access to a BF to get the message builder
factory.

Use mocks where needed for test cases.

Ran with SI 4.0.0.BUILD-SNAPSHOT with environment variable:

	SI_FATAL_WHEN_NO_BEANFACTORY=true

which forces a hard failure instead of just a log message.

XD-1539 revisited

The catch block on line 596 of ContainerRegistrar only included KeeperException,
but an IllegalStateException is thrown in the case where the CuratorFramework is
not in a STARTED state, and the checkExists() method is called.

For now, I've widened the catch block to Exception itself.
