Adam Harwell 29a2ec7187 Deprecate the Spares Pool feature for removal in X
Use of the spares pool was originally recommended to increase provisioning
speed, but since Nova's server groups do not support adding existing VMs,
Octavia cannot support use of the spares pool with the Active-Standby
topology. Since this is our recommended topology for production deployments,
and speed is less essential in development/testing environments (the
only place we could recommend the use of Single topology), the overhead of
maintaining spares pool support exceeds its theoretical usefulness.

Spares pool support is deprecated, pending removal in the X release. Use of
the spares pool was originally recommended to increase provisioning speed,
but since Nova's server groups do not support adding existing VMs, Octavia
cannot support use of the spares pool with the Active-Standby topology.
Since this is our recommended topology for production deployments, and
speed is less essential in development/testing environments (the only place
we could recommend the use of Single topology), the overhead of maintaining
spares pool support exceeds its theoretical usefulness.
