Create scripts to run YCSB

[eolivelli]

As we are using the YCSB suite https://research.yahoo.com/news/yahoo-cloud-serving-benchmark/ it would be great to have a bash script to run YCBS workloads directly on the compiled artifacts

for standalone instances it would be very useful
parameters:

• YCSB directory
• HerdDB JDBC artifacts position
• HerdDB Service ZIP position

the script is in ycsb-runner directory, you have to download and unzip YCSB separately
for instance
./run-jcsb.sh ABS-PATH-TO-YCSB ABS-PATH-TO-HERDDB-SERVER workloada
