fix(api,nsmaster): fix max body size to accommodate catalog zone

The catalog zone request currently has 2.9 MB. The previous limit
for request bodies in nsmaster was 2 MB. This comit sets it to
16 MB which should suffice for the forseeable future.

Future work on the replication mechanism can entirely elimitate
the need to provision the zone atomically, so that smaller chunks
can be committed.
