Functionality for noRandomDuplicates parameter and custom Stream options with seeding

[allenshen13]

Add NoRandomDuplicates and Custom Stream Seeding Features

NoRandomDuplicates:

Prevents duplicate query selection during random execution until all queries have been executed at least once.

When true: Creates shuffled sequences of all queries, executing each query once before repeating any.

{
  "random_execution": true,
  "randomly_execute_until": "20",
  "no_random_duplicates": true,
  "query_files": [
    "../queries/complex-1.sql",
    "../queries/complex-2.sql",
    "../queries/complex-3_ordered.sql",
  }

Custom Streams and Seeding:

Purpose: Enables deterministic random behavior across stream instances while maintaining reproducibility.

Individual Stream Seeds:

{
  "streams": [
    {
      "stream_name": "query_stream.json",
      "stream_count": 3,
      "seeds": [12345, 67890, 11111]
    }
  ]
}

Base Stream Seed (applied to all instances with offset for each one):

{
  "streams": [
    {
      "stream_name": "query_stream.json", 
      "stream_count": 3,
      "seeds": [54321]
    }
  ]
}
