We can perhaps get away with a simple mechanism: we define a generic
"instance-type" constraint. If the name of that constraint matches
exactly something that is available in the API endpoint being used
(not just provider type, since we can have multiple API endpoints with
the same provider type yet different machine types), we use it. If it
does not match any, the script errors out so we can catch typos and
actual errors. In a second moment, we can provide a mechanism for
people to provide their own custom mappings tied to their environment
("in this environment t1.micro means 1 CPU and 512MB of memory").
