I’m kinda surprised we need all these extra syntaxes — we’re creating a new table so create and in particular ifnotexists seem implied? I donno I don’t feel strongly about it

@rolandcrosby do you have any inputs on this? This is w.r.t what column qualifiers we support when grouping into a FAMILY. I agree with David, I just copy-pasted from the qualifiers CREATE and ALTER support.

yeah I would just support the "FAMILY" syntax in CTAS; don't think there's any reason to complicate things by adding redundant "create" or "if not exists" qualifiers for column families here.

This change introduces grammar to support user defined column families. We are able to entirely piggyback on the existing CREATE TABLE logic handling this, and thus there are no changes outside of `pkg/parser`. Added logic tests to verify behavior. Release note (sql change): CREATE TABLE ... AS allows user defined column families.
