(PDB-81) - Adding a JDK 1.6 deprecation warning message

Adding a warning message to the console and the logs.  The bootstrapped default logger is logged when the user provided log config is not there (such as invoking the version command). It's then logged in services.clj as well (after the logging config would have been applied).

Made some some changes to c.p.p.core.clj to allow testing of the
main launch function (and the deprecation messages). Tried to test commands failing (i.e. running services without a config) but found that cli (in kitchensink) also calls System/exit.  I talked with Chris about this and they have already made changes away from using System/exit over there.  That scenario should hopefully be tested in a newer version of kitchensink.
