Hybrid Connections - Allow them to be designated to a slot and not swapped
Allow Hybrid Connections to be pinned to a specific slot like app settings and connections strings. Especially since connection strings and hybrid connections are typically codependent.
Hybrid connections are designed to retrieve data from on-premises sources. 99% of the time, you don't want to swap that. I don't want a swapped slot to start pulling data from somewhere else.
Say you have a Production and UAT slot. When I promote UAT into production, I still want the production slot to still use the production hybrid connection and the same for UAT.
