LBaaS: unify haproxy-on-host plugin driver and agent

Unifies haproxy reference implementation to make common agent based plugin driver
which is suitable for all vendors who wants to use async mechanism.

 - Agent API as well as device driver API changed to handle
   loadbalancer objects individually;
 - Agent loads device drivers according to config;
 - LogicalDeviceCache class was removed from agent as it was used only
   as a list - to put and remove entries ant check whether entry is in or not.
   It was replaced with instance_mapping dict in agent to store known instances and
   corresponding device_drivers;
 - Agent reports which device drivers are supported (needs for scheduling on plugin side);
 - Agent-to-plugin API was extended to provide an ability for agent to update
   statuses of pools/vips/members/health_monitors;
 - Vendor should only implement device driver; plugin driver just needs
   to inherit AgentBasedPluginDriver and override device_driver member;
 - This patch doesn't move files to make review easier;
   all rename/replace will be done in a subsequent patch;

DocImpact

NOTE: Since the change in the agent RPC API is backward-incompatible
(major RPC version change), LBaaS server-agent communications will be
completely broken until both sides are upgraded so users will be unable to
create new or update existing HAProxy loadbalancer instances during upgrade

Raise better exception if duplicate security groups

Previously a 500 error was raised if one was trying to launch an instance
with a security group that shared the same name as another security group.
With this patch a more clear error message is raised.
