Code Issues Proposed changes

Extend methods for network segment range support 

This patch extends the ML2 type driver abstract methods
``reserve_provider_segment`` and ``allocate_tenant_segment`` with
``filters`` used as search criteria for the segment allocation support
when network-segment-range extension is loaded.
