Michael Johnson 2897b340f7 Fix health monitor type "PING" to use icmp ping
Currently with Octavia, if the user specifies a health monitor of type
"PING" we are still using a TCP connect to check for health.
This patch fixes that to actually ping the member to validate health.

issues:
- |
Amphora images with HAProxy older than 1.6 (CentOS 7, etc.) will still
use health monitor type TCP when PING is selected by the user.
upgrade:
- |
Amphora will need to be updated to a new image with this version of the
agent and ping-wrapper.sh script prior to updating the Octavia controllers.
If a load balancer is using a health monitor of type PING with an
amphora image that has not been updated, the next configuration change to
the load balancer will cause it to go into an ERROR state until it is
failed over to an updated image.
fixes:
- |
Fixed an issue where health monitors of type PING were really doing a
TCP health check.
