# The purpose of this script is to make it easier for developers to setup new benchmarks.
# As input the benchmark name is expected, which is used for the docker image tag and k8 namespace.
# This script does the following:
#
# 1. Build the current branch
# 2. Build the docker dev image
# 3. Publish the docker image
# 4. Setups new namespace
# 5. Configures the benchmark
# 6. Deploy's the benchmark

# Contains OS specific sed function
