add new command line handler
New command line handler with pluggable classes. Task subcommand added. To run a scenario: yardstick -d task start samples/ping.yaml $ yardstick -h usage: yardstick [-h] [-V] [-d] [-v] {task} ... Command-line interface to yardstick optional arguments: -h, --help show this help message and exit -V, --version display version -d, --debug increase output verbosity to debug -v, --verbose increase output verbosity to info subcommands: {task} $ yardstick task -h usage: yardstick task [-h] {start} ... Task commands. Set of commands to manage benchmark tasks. optional arguments: -h, --help show this help message and exit subcommands: {start} $ yardstick task start -h usage: yardstick task start [-h] [--keep-deploy] [--parse-only] [--output-file OUTPUT_FILE] taskfile Start a benchmark scenario. positional arguments: taskfile path to taskfile optional arguments: -h, --help show this help message and exit --keep-deploy keep context deployed in cloud --parse-only parse the benchmark config file and exit --output-file OUTPUT_FILE file where output is stored, default /tmp/yardstick.out JIRA :- Signed-off-by: Jo¶rgen Karlsson <jorgen.w.karlsson@ericsson.com> Change-Id: If0672594efa4c94c94ebb73f0bc97ecfe3e00c62
