We used to generate the ID, if the caller didn't specify it. That's bad
practice, however, because network is never fully reliable, so it's
possible we create a new tenant but the caller doesn't know about it,
and because it doesn't know the tenant ID, it has no way of retrying or
checking if it succeeded. To discourage that, make it mandatory. The web
control plane has not relied on the auto-generation for a long time.

Adds a set of tests on the storage Docker images before they are pushed
to the public registries:
* tests that pageserver binary has the correct version string (other
binaries are built with the same library, so it should be enough to test
one)
* tests that the compose file set-up works and all components are able
to start and perform a single SQL query (CREATE TABLE)
