Subject: Provide yardstick-trusty-server.tar.gz for lxd scenario

JIRA: YARDSTICK-325

This patch removes ping_lxd_test.yaml and changes vm image used for lxd senarios.
In the *-lxd-* scenariois, Cirros LXC 0.3 image will be used for Ping test case.
For yardstick generic test, a dedicated yardstick vm image will be used.
