Title:
  neutron-lbaas health monitor timeout and delay values interpreted as
  milliseconds

Status in neutron:
  Fix Released
Status in octavia:
  Fix Released

Bug description:
  The timeout and delay values on the health monitor objects in Neutron
  LBaaS are purportedly in units of seconds, but the numeric value is
  passed all the the way down to the HAProxy configuration[1] file (in
  both the HAProxy namespace driver and Octavia) where it is interpreted
  in milliseconds:

  * https://cbonte.github.io/haproxy-dconv/configuration-1.5.html#4.2-timeout%20check
  * https://cbonte.github.io/haproxy-dconv/configuration-1.5.html#5.2-inter

  Due to this unit mismatch, a user may configure a pool with a
  reasonable 10 second timeout, and the service may appear to function
  normally until even a small load causes the backend servers to exceed
  a 10 millisecond timeout and then they are removed from the pool.

  A timeout value less than one second is useful some settings, such as
  monitoring a pool of backend servers serving static content, let the
  database field stores this value as an integer.
