Add container pull option to install.yaml

Supported Yardstick installation modes in yardstick.yaml: baremetal
and container. First is used to install Yardstick on baremetal,
another is used during docker build to install Yardstick in container.

Added third option: 'container pull': to pull docker image
(opnfv/yardstick) from Docker hub and start container.

JIRA: YARDSTICK-1392
