Comment 1 for bug 1860703

Below linked is a branch to implement this:

https://git.evergreen-ils.org/?p=working/Evergreen.git;a=shortlog;h=refs/heads/user/miker/lp-1860703-http_action_trigger_reactor

From the commit message:

There is currently no stock mechanism for pushing information out of Evergreen to trigger activities in external systems. Third party discovery systems, among other external systems, would benefit from the ability to be alerted of changes to data within an Evergreen instance.

This commit adds such a capability by supplying a new A/T reactor module that can make HTTP requests that supply data to a third party endpoint.

To support the discovery system use case, this commit also adds a new A/T hook, bre.edit, fired whenever a bibliographic record is modified due to staff interaction.
