Add support for the label listing

[lachmanfrantisek]

• Add listing labels with ability to copy them to other repo.

Usage: tool labels [OPTIONS] [REPO]

  List the labels for the project. This is how you can select a repository
  for Github: <namespace>/<project>.

Options:
  -s, --service TEXT  Name of the git service (e.g. github/gitlab).
  -c, --copy TEXT     Copy labels to another repo.
  --help              Show this message and exit.

$ tool labels -c user-cont/colin -c user-cont/conu

There is only a problem with the descriptions -- the GitHub API does return them...

Subcommand split:

$ tool list-labels --help
Usage: tool list-labels [OPTIONS] [REPO]

  List labels for the project. This is how you can select a repository for
  Github: <namespace>/<project>.

Options:
  -s, --service TEXT  Name of the git service (e.g. github/gitlab).
  --help              Show this message and exit.

$ tool update-labels --help
Usage: tool update-labels [OPTIONS] DESTINATION [SOURCE]

  Update labels of other project. Multiple destinations can be set by
  joining them with semicolon. This is how you can select a repository for
  Github: <namespace>/<project>.

Options:
  -s, --service TEXT     Name of the git service for destination (e.g.
                         github/gitlab).
  --source-service TEXT  Name of the git service (e.g. github/gitlab).
  --help                 Show this message and exit.

@TomasTomecek I have two questions:

• Any idea to achieve multiple destinations than this:

  $ tool update-labels user-cont/colin\;user-cont/conu user-cont/tool

• Do we need to be consistent with the REPO argument in other commands? Is the destination ok?

Thanks.

I've also added support for the gitlab. Some notes about that:

• The colour format differ (Github does not have # at the start). --> Currently, I am converting the colours on the update. Does it make sense to use some common format for list-labels?
• I've added --source-service to allow different service for the source and destination. (If there are multiple destinations, all will have the same service.)
• In the future, we can have some file import/export for the sync.

    Any idea to achieve multiple destinations than this:

$ tool update-labels user-cont/colin\;user-cont/conu user-cont/tool

how about $ tool update-labels --source-repo https://github.com/user-cont/kwaciaren user-cont/x user-cont/y. --source-repo would default to repo in PWD.

Do we need to be consistent with the REPO argument in other commands? Is the destination ok?

Yes, that's fine. I'm working on configuration PR and let's discuss over there once I open it.

The colour format differ (Github does not have # at the start). --> Currently, I am converting the colours on the update. Does it make sense to use some common format for list-labels?

Personally, I don't care.

I've added --source-service to allow different service for the source and destination. (If there are multiple destinations, all will have the same service.)

This is pretty nuts!

@TomasTomecek I've done as you wrote...

[TomasTomecek]

Well done!
