---------------------------------------------------------------
h1. Design
For the function timestampadd, calcite for kylin will transfer to datetime_plus
to fold the constant, however, the calculation does not support string. If the
first parameter is year/day/month/quarter, the constant folding works but gives
wrong result. In order to support this, add some functions in the calcite for
kylin to support operations on string type.
