Update this repo

[dylan-azucena]

I am attempting to configure the pacemaker AG resource on Ubuntu 20.04 and Pacemaker 2.0.3, with SQL Server 2019. I am running into issues and it would be helpful to have the source of the ag-helper script especially. Based on the behavior I'm seeing it is clear that ag-helper (and/or the libraries it uses) has changed significantly since the snapshot in this repo. The request is to update this repo with a new snapshot if possible.
