[Ros-release] how to migrate 4-month-old GBP repo to latest …

I've seen changes in the way bloom formats its release repositories. When
dealing with the previous layout it seems to upgrade automatically.

But, I am trying to release image_common, which has not been released for
about four months. Its GBP repo looks strange, it has a copy of the code in
"master" and a tracks.yaml file in the "bloom" branch. I know the format
has changed since then, but bloom does not seem to be able to find the
tracks.

https://github.com/ros-gbp/image_common-release

Any suggestions for how to get this repo working with the current bloom?

joq@vision-4:image_common-release$ git-bloom-config show hydro
Track 'hydro' does not exist.
joq@vision-4:image_common-release$ git co bloom
Switched to branch 'bloom'
joq@vision-4:image_common-release$ ls
bloom.conf  tracks.yaml
joq@vision-4:image_common-release$ git-bloom-config show hydro
Track 'hydro' does not exist.
 joq@vision-4:image_common-release$ cat tracks.yaml
tracks:
  hydro:
