Ask about remoteBranch

Hi,

I have repo with multiple branches. I want to choose what will be remote branch when I create MR. I propose some option in settings.json, lets say "gitlab-mr.askRemoteBranch" or "gitlab-mr.listRemoteBranch. This option will list branches in repository during create MR and I would choose target branch. ;-)

Actual I have 3 option:

• default branch in GitLab
• default branch in settings.json
• master/origin

What do You think about this ?
