There was no validation for the provided ip prefix. This just adds a simple parse using netaddr and explodes with appropriate message. Also makes sure ip prefix _is_ cidr (192.168.1.1-->192.168.1.1/32). Validation occurs at the attribute level (API model) as well as at the db level, where the ethertype is validated against the ip_prefix address type. Unit test cases added - bad prefix, unmasked prefix and incorrect ethertype. Also adds attribute test cases for the added convert_ip_prefix_to_cidr method Change-Id: I71fb8c887963a122a5bd8cfdda800026c1cd3954 Closes-Bug: 1255338
