Improve RandomNumberGenerator interface

Description
The quantification work requires the Sobol sequence generator from the GSL library.
The current random number generator interface is limited to 1D numbers. Create an interface for generating a point in ND space along with a specialized interface for a seeded pseudo-random number generator.

Add a NDPseudoRandomNumberGenerator. Refs #5322
Uses a single generator to allow easy construction of an ND point from pseudo-random numbers thereby presenting a cleaner interface inline with the other ND generators.

Improve performance of random number generator. Refs #5322
Return is now by reference & there is a performance test.

This ticket has been transferred to github issue 6168
Created an NDRandomNumberGenerator interface. Refs #5322
The Vates quantification requires using the Sobol sequence for producing a point in ND space. The interface as it was made it difficult to swap out other random number generators. There is now a generic ND interface that returns a vector of numbers.
