Sometimes S3 Bucket doesn't get created

[joehoyle]

Steps to reproduce:

1. composer server start
2. Visit https://s3-console-$project.altis.dev/buckets, login with admin password
3. Observe no buckets exist

This looks like a race condition between the s3 and s3-sync service. s3-sync creates the bucket and sets the permissions. I think if minino isn't up and running set the mc mb -p request fires too early. Subsequently, if I do wait for minio to start and then manually run mc mb -p local/s3-$project && mc policy set public local/$project and then I see:

mc mb -p local/s3-$project && mc policy set public local/s3-$project
Bucket created successfully `local/s3-$project`.
mc: <ERROR> Unable to set policy `public` for `local/s3-$project`. The specified bucket does not exist.

And then I run it again and it works, so there seems to need to be more time between the make bucket request and the ACL public request.
