feat: Optional Benchmark Warmups

[stanbrub]

• Added optional benchmark warmups that do a partial run of exactly the same benchmark before the measure benchmark runs
• Tested to see nearly two thirds of JIT compile time move out of the measured operations
• Added default warmup.row.count = 0 to release, compare, adhoc and nightly workflow files
• Reorganized static and incremental query template generation to allow multiple runs with different row counts
• Reworked the "read" logic to use part of the same data use for the benchmark in the warmup (eliminates two data gens)
