cmd/jujud: rationalised version number handling in upgrade-steps worker

1. Use version.Number's in logs and status output throughout instead
of version.Binary's. The series and architecture is irrelevant to the
upgrade process and including it just adds unnecessary verbosity.

2. The check for an already completed upgrade has been moved earlier
to avoid unnecessary initialisation.

3. New upgradeWorkerContext attributes have been added to make the
from version more accessible and the target version shorter to read
and write.
