Make a new bucket with "US" location to replace archive-mlab-oti

[cristinaleonr]

The location for the archive-mlab-oti bucket in the mlab-oti project is "us-central1" (single region).

We want the bucket location to be "US" (multi-region) to allow for greater flexibility and for consistency with the corresponding buckets in mlab-sandbox and mlab-staging.

According to the documentation for GCS, it is not possible to change a bucket's location after it's created. We will have to create a new bucket with the location set to "US" and transfer the existing data to it.
