Add an endpoint to get final SQL query (not parameterized)

[ThomasKientz]

Is your feature request related to a problem? Please describe. The endpoint /cubejs-api/v1/sql returns a parameterized query which is of no use.

Describe the solution you'd like An endpoint that returns the final SQL request ready to be pasted in DB ide (to debug and test).

Describe alternatives you've considered Manually replace the ? with filters value but it is error prone and tiresome.
