tag_release can crash with ReadTimeout when rolling back changes

[kdmccormick]

Description

Scenario: When rolling back changes, the tag_release script might hit a ReadTimeout, for whatever reason.

Desired behavior: When rolling back, any ReadTimeout would be handled by logging & re-trying. The re-trying would continue until the user manually cancelled the script with Ctrl-C.

Actual behavior: Script does not handle ReadTimeout; it crashes. Not all changes are rolled back.

This issue is based on a memory and a brief note I made during the Nutmeg release. If this can't be reproduced or doesn't seem valuable to worry about, then feel free to close this.
