88dd89b2ff
The patch makes the following changes: * adds new attribute of the pool: provider, which is provider name as it is written in configuration * adds support for multiple plugin drivers for loadbalancer * cleans up healthmonitor-related plugin driver API Drivers should work with healthmonitor associations only * adds ability to update provider attribute for the pool used to reassociate pools with new providers in case their providers were removed from configuration implements blueprint lbaas-integration-with-service-types DocImpact Change-Id: I4295c9bcceb38e60f813d5596af48bd8194c1c9b
