Add convert() to Coder
This addresses Liam's review comment about moving the "translate" method from the actor Util class into policy-common. Added a method to Coder to convert from one object type to another (e.g., from a Map to a POJO, or vice versa). Issue-ID: POLICY-2363 Signed-off-by: Jim Hahn <jrh3@att.com> Change-Id: I2a0b5ab4ce4b0eeda216a57cbe23a8bb64f64940
