Add the new DreamCompute cloud

It does things the happy way - direct routing of IPv4 and IPv6. However,
it's a respin, so we're naming it dreamcompute rather than dreamhost so
that users don't get broken by the shift.

Remove dreamhost from the docs - people looking at documentation should
be using the new region.
