TNL-1955

Problem:

Intermittent "cb() never called!" errors on npm installs for platform.
This is likely due to a race condition on installing OS-specific bits that are built during time of install. When more than one compilation takes place at one time, this error can occur.

Workaround:

Detect the error and re-run the install. (When retrying, one or all of the bits have been compiled. So running it again just finishes the install.)

Added the templates for email subject, email body and the changes in submit_feedback function that now conditionally sends emails.

Suggestions.
