Dots in aggregation names can lead to tricky parsing situations, like being unable to sort by agg names with dots. Rather than introducing a lot of complex parsing code, we should just deprecate dots in agg names. This puts them inline with the restrictions on field names too.
This PR adds a deprecation logger and a note in the docs, letting us remove them in 8.0.
It isn't strictly a 7.0 deprecation (I would like to backport it to 6.4), but I thought it made sense to include in the 7.0 migration guide in case people upgrade directly from 6.3 to 7.0
