Subject: HONEYCOMB-293 - Memory benchmarking

Contains configuration for benchmarks:
- Honeycomb on rest(just infra, no data)
- Honeycomb with 1000 data nodes
- Honeycomb with 10000 data nodes

Each benchmark outputs two files:
- out_path_name-HeapMemoryUsage.csv
- out_path_name-NonHeapMemoryUsage.csv

Both files are in format :
committed,init,max,used
109576192,109051904,1525153792,12194752

Data sample sizes can be easily adjusted, just by changing
start parameter -DsampleSize
