d0a67878a3
This change adds a plugin interface so that driver can be loaded dynamically. Instead of importing each driver in the launcher, provider_manager and config, the Drivers class discovers and loads driver from the driver directory. This change also adds a reset() method to the driver Config interface to reset the os_client_config reference when reloading the OpenStack driver. Change-Id: Ia347aa2501de0e05b2a7dd014c4daf1b0a4e0fb5
