This updates the `template` subcommand to be `generate`. The `template`
usage will continue to work as an alias to `generate`. A new `switch`
command is added that will manage both `rpm-ostree rebase` and
`rpm-ostree upgrade` and is fully replacing the respective subcommands
as a breaking change.
The new `switch` command is under the feature flag `switch` and will
currently only build for the `main` branch builds until it is moved as a
default feature (`v0.9.0`).
Closes#159
Add a bug report + completions command(not complete yet) so that new
users can easily submit bugs to us, and I wanted completions for bb
(super easy with clap)
