LBaaS Common Agent-based Driver

Rationale

Haproxy-on-host reference implementation which is using agents is quite specific:

• with haproxy it is easier to deploy the whole loadbalancer config from scratch every time then to create/update/delete separate components
• namespace driver needs virtual interface driver on init, other drivers may have their own specific parameters

So it is useful to unify reference agent implementation to:

• make it suite any driver which wants to use async mechanism
• have single lbaas agent type and hense single agent scheduling mechanism

What is required:

1. Revision of agent API
2. Revision of agent loading device driver(s) mechanism
3. Add optional device_driver field to ServiceProvider. Should be passed to lbaas agent if present.
