Support other object storage regions

[smothiki]

Currently, the Minio client library's MakeBucket call is the only one that supports regions. This may be enough to support other regions, but our code doesn't look for the region parameter or pass it to that MakeBucket call (see https://github.com/deis/builder/blob/master/pkg/gitreceive/build.go#L103).

For an internal look at the minio-go client logic, see the following lines:

• Where it detects whether the given URL is an Amazon endpoint
• Where it fetches the S3 URL

since we want to move away from minio in rc1.This shouldn't be an issue the PR #262 is merged.
