The changes look good. Unfortunately for me, I didn't consider CREATE INDEX when parsing online DDL; while it's a valid query, I only planned for ALTER TABLE. Moreover, gh-ost only supports ALTER TABLE form.

What I would like to consider is to have a func (*CreateIndex) ToAlterTable() *Statement function. Given the fields in CreateIndex struct I feel like this is reasonable to accomplish. What do you think?

Yes, we can have that function for converting CREATE INDEX query to ALTER TABLE. For now the focus is on mysql compatibility and I will revisit this when the planning and parsing for other constructs is done too. I will add it to the TODO list https://github.com/vitessio/vitess/projects/7. Is that alright?

TabletServer now uses the AST generated query in case it is fully parsed
