[rbridge] How many "priorities" are there?

Is there just a single priority for an RBridge, that is used for all the
priorities, or are there separate ones for:
a) priority for becoming DRB on a layer 2 cloud
b) priority for becoming the "CSNP-generator" for announcing VLAN x
endnodes? And if so, is there a separate priority
per VLAN, so you can have low priority for one, and high for another?
c) priority for becoming a tree root?
d) priority for owning a chosen (as opposed to configured) nickname?
There might even be more cases where we use the term "priority".
I'd guess that a) and c) might be things that customers would want to
configure. I think that b) is something that
should be just a flag "I implement endnode advertisements (learning from
and advertising)", though perhaps
the flag should be per VLAN. I don't think d) matters, and
we could just use the same priority as for DRB.
