It is more natural for the label and unlabel commands to exist as
subcommands of the object they are labelling, i.e. issues and
patches.
Remove the `rad label` and `rad unlabel` commands, moving their
functionality to the `rad issue` and `rad patch` commands. The
`rad-issue.md` and `rad-patch.md` tests are modified to include a
label test.
The `rad patch show` command did not support showing labels as part of
its output. This was also included to confirm the test above was working.
