Add gson adapters for special field types
Added type adapters for Instant, LocalDateTime, and ZonedDateTime. UUID seems to work already. Added new Coder that offers an alternative encoding for Instant. Issue-ID: POLICY-1625 Signed-off-by: Jim Hahn <jrh3@att.com> Change-Id: I5230fa7fe955d78c5f2da1316cb1504b5875ea84
