> Add {{RAND}} function, returning {{DOUBLE}} values in the range 0..1. It has variants {{RAND()}} and {{RAND(seed)}}.
> Also, add {{RAND_INTEGER(seed, bound)}}, support for a seed when generating random integers.
> To support seeds, the random function needs to have state. The random number generator is initialized, using the seed, on first use, and subsequent calls use the same random number generator. So, we are building on CALCITE-1548.
