Could not create git bare repository

[gabrielclima]

I'm trying to test Tsuru env, i installed the stack with Docker Compose, using the Tsuru tutorial.

When i try to create a new app using tsuru-client with the command ./tsuru app-create test-py python3 --team=admin, returns the error bellow:

Error: tsuru failed to create the app "test-py": Could not create git bare repository: exit status 128. fatal: cannot mkdir /var/lib/gandalf/repositories/test-py.git: Permission denied

i ran _ docker exec -it 16b84a7256cf chown git:git /var/lib/gandalf/repositories/ and now i can create respositories:

➜  Downloads _ docker exec -it 16b84a7256cf chown git:git /var/lib/gandalf/repositories/
➜  Downloads ./tsuru app-create test-py python3 --team=admin                            
App "test-py" has been created!
Use app-info to check the status of the app and its units.
Your repository for "test-py" project is "git@localhost:test-py.git"

i believe this error can be resolved adding chown git:git /var/lib/gandalf/repositories/ line to gandalf docker-entrypoint.sh file.

its sounds correct? if yes, can i open the PR with this correction?
