Rationalize system host names

Closes #67

See merge request !110

See, it makes more sense.

we deleted it already but it got brought back

Regularize (somewhat) the definition of grids for Morph

See merge request !109

Also this no longer needs to be rec

It is no longer required to add IP addresses to the Vagrant-generated ssh
configuration because the Vagrant-configured hostnames now match up with the
names morph will try to use to connect to the VMs.

Just require hostName and domain instead of an extra publicIPv4 option.  Leave
behind a similar option, `publicAddress`, just in case it needs to be
overridden at some point, but stop supplying a value for it anywhere.

Maybe later?

Put its contents in it and then use them from there instead of importing them
all over the rest of the code.
