Hi [~rustyrazorblade],

patch with this implementation. Waiting for more information on #3.

> If you pass an invalid datacenter to nodetool rebuild, you'll get an error
> like this:
> {code}
> Unable to find sufficient sources for streaming range
> (3074457345618258602,-9223372036854775808] in keyspace system_distributed
> {code}
> Unfortunately, this is a rabbit hole of frustration if you are using caps for
> your DC names and you pass in a lowercase DC name, or you just typo the DC.
> Let's do the following:
> # Check the DC name that's passed in against the list of DCs we know about
> # If we don't find it, let's output a reasonable error, and list all the DCs
> someone could put in.
> # Ideally we indicate which keyspaces are set to replicate to this DC and
> which aren't
