basic example of spinning up an alloydb instance

[drewwells]

the process involves two steps because we don't know the
service attachment url at declaration time

after serviceattachemnt url is available, provision a composition
that will setup forwarding rules to the google vpc and a hostname
to resolve the psc hostname
