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,
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.
