@deweter can you please check why go.sum was changed and if that's correct please run make tidy.

I believe that azuresqlmanagedqueries.go should be changed as well, since managed instances can be part of AGs.

@spaghettidba - I changed it. Initially, I skipped it as I didn't test it, but in general I do agree that the error could appear most probably there too.

@srebhan - Sorry, my mistake - I removed a change to go.sum

@spaghettidba and @Trovalo any comments?

[srebhan]

Code-wise this looks good to me. Waiting for @Trovalo's ok on this...
