This PR refactors and reorganizes a lot of code. It attempts to organize
things in a way that allows to keep more things private. Conversely, it
made the fields of many data-only structs pub and removed the creator,
accessor, and unpack methods for those.
The PR deliberately avoid any functional code changes given that due to
its sheer size, it is essentially unreviewable.
This is also why it stopped short of re-organizing the structure of the
actual server, ie., the Krillserver and the daemon::http module which
currently have a rather blurry distinction. A follow-up PR will create a
more clear separation but this requires code changes.
This PR changes how the clients -- krillc, krillta, as well as the
integration tests -- work to better fit the derive model provided by clap.
This results in basically everything in the cli module and all the
integration tests being different now.
The PR slightly changes the options for both krillc and krillta. For krillc,
the --server, --token, --format, and --api options are now before the first
subcommand (since they affect all commands). For krillta, those options are
now after krillta proxy but before the next subcommand, while --format is
now after krillta signer.
This PR also removes client support and integration tests for RTA.
This is a breaking change.
