Command line flag to solve GitHub/GitLab ambiguity

[cdboer]

Is your feature request related to a problem? Please describe.
GitHub/GitLab detection is really naiive. It only tests for occurence of "github" or "gitlab" strings in the given extraction url. GitLab projects can be called r'.*github.*' which would lead gitlab2prov to try to use the GitHub API for a project hosted on gitlab.

Describe the solution you'd like
Users should be able to declare which platform the project is hosted on by declaring a command line flag/argument such as --platform for the extraction subcommand. Additionally we should think about making a test request to the project url to find out whether its hosted on gitlab or github.

• Command line flag
• HTTP request to find automatically resolve the platform

Maybe it would be better to split gitlab2prov & github2prov into two seperate cli tools. E.g.

github2prov

and

gitlab2prov

they could share commands like load, save, combine, etc. and have their own subset of commands with gitlab/github specific behaviour such as merge-duplicated-agents etc.

@click.group()
def gitlab2prov(): 
    pass

@click.group()
def github2prov():
    pass

@click.command()
def example():
    pass

# add gitlab specific cmds
gitlab2prov.add_command(example)
gitlab2prov.add_command(example)
# add github specific cmds
github2prov.add_command(example)
github2prov.add_command(example)

Note: If you split github & gitlab behaviour into seperate cli's you can't use a single config file containing github & gitlab urls. This should be noted in the README
