Comment 7 for bug 1748265

Thanks Gary, Thanks Dawn.

I have pushed an additional branch to:

https://git.evergreen-ils.org/?p=working/Evergreen.git;a=shortlog;h=refs/heads/user/berick/lp1748265-hold-list-sms-carrier

This branch includes mine and Dawn's sign-off on Gary's commit.

It also includes a commit to support the "include_sms_carrier" option to the holds API to add the server-side component matching Gary's changes. This means the data will be retrieved with the hold instead of requiring the grid make a batch of API calls after the fact, which would negatively impact render speed of the grid.
