Rest servers should return 400 for bad syntax JSON
Modified common RestServer to inject an exception handler into the list of providers so that it returns 400 instead of 500 for JSON parsing errors. Change-Id: I7c77625e3531e26413d72cc386296a709946cda2 Issue-ID: POLICY-1725 Signed-off-by: Jim Hahn <jrh3@att.com>
