Michal Arbet 7c2b4bead2 Add way to change weight of haproxy backend per service
This patch adding option to control weight of haproxy
backends per service via host variable.

Example:

[control]
server1 haproxy_nova_api_weight=10
server2 haproxy_nova_api_weight=2 haproxy_keystone_internal_weight=10
server3 haproxy_keystone_admin_weight=50

If weight is not defined, everything is working as before.
