m/test: refactor cluster launch code, use for e2e tests

This is a light dust-off pass for the existing cluster launch code.
Notably, we separate Metropolis-specific code into a subpackage
(allowing us to make the package itself depend on the required
node/kernel images, without introducing dependency loops or unnecessary
dependencies on the Metropolis node image).

We also make the LaunchCluster code return an already authenticated
Management client, and subsequent changes will use this client to add
more nodes to the running cluster.

We then move the E2E test to use LaunchCluster instead of LaunchNode, in
preparation for running a multi-node cluster in the E2E test.

We also add some more log calls and clean up the existing ones to make
it clear which subsystem (launch, launch/cluster or e2e) is respondible
for each message.
