> Our create table methods in HBaseAdmin are synchronous from client POV.  However, underneath,
we're using an "async" create and then looping waiting for table availability.  Because the
create is async and we loop instead of block on RPC, we don't expect RPC timeouts.
> However, when creating a table with lots of initial regions, the "async" create can actually
take a long time (more than 30 seconds in this case) which causes the client to timeout and
gives impression something failed.
> We should make the create truly async so that this can't happen.  And rather than doing
one-off, inline assignment as it is today, we should reuse the fancy enable/disable code stack
just added to make this faster and more optimal.
