I added token replacement for the username, password, and manager context fields.

Note that only the Tomcat changes have been tested.

Also, instead of performing all of this token replacement in the subclasses we could just go ahead and apply the token replacement in DefaultCargoContainerAdapterImpl.setConfiguration(). Upstream may prefer that approach. I didn't make the change because it would require more testing to make sure that it didn't break stuff.
