This script helps synchronize a Github PR to Bitbucket when the PR is

developed and opened on Github. It will mirror the Github PR to bitbucket,

create an internal tracking issue and a PR for it.

Run it without any arguments, it will interactively offer Github PRs that

are not mirrored from the internal CI to Github.

You can re-run the script to force an update of the internally mirrored

branch if the Github PR changed.
