Epic Name: columnstore window function parity

 Description   

Previously ColumnStore 1.0 had a custom fork of the mariadb server code to support window functions. Migrating CS to 10.2 has identified that there is a gap in functionality provided by CS not in 10.2. This epic covers the individual feature requests to close this gap. All of these are ANSI specified or de-facto specified by other databases so not a one off.
