region vs regionserver coprocessors
Looking at the coprocessor load code, and at the documentation...
I've noticed that coprocessors like AccessController, TokenProvider, ...
are region coprocessors.

This means that for each region there's a new instance of TokenProvider,
AccessController, ...

Is there a reason to not have them as RegionServer coprocessors (loaded
only once per RS)?

also the HRegionServer.getCoprocessors() seems to not print the
regionserver coprocessors but just the hlog + region coprocessors.
