Avatica tags in Calcite repository

[Francis Chuang]

I just noticed that tags for Avatica are being pushed to the Calcite 
repository [1].

Is this intended? My understanding is that since Avatica was split into 
its own repository in early 2016, it's considered a separate sub-project 
of Calcite.
