no, Michael it is not yet modifiable. 
it could be, but with mentioned issue with upgrades,
i made it nonmodifiable (i.e. master on start checks
that it not differ from what config denotes) and if
it differs it overrites it. 

i think that next step could be some meta version, which
will help upgrade code to do right things (like it should
know how to upgrade meta between versions, like
database migration does). And when we will do that -
we can get truly :) modifiable meta.

> In HBASE-13087 stumbled on the fact, that region servers don't see actual meta descriptor,
they use their own, statically compiled.
> Need to fix that.
