Major refactoring of the BMv2 protocol module (onos1.6 cherry-pick)
- Created 3 separate sub-modules: API (doesn't depend on
Thrift), CTL (depends on Thrift), THRIFT-API (to generate Thrift
sources)
- Implemented 2 new services (for device configuration swapping and
table entry management) needed to distribute BMv2-specific state
among ONOS instances.
- Implemented a BMv2 controller (previously other modules where
using separately a Thrift client and a server)
- Added a default BMv2 JSON configuration (default.json) and interpreter
to be used for devices that connect for the first time to ONOS.
This allows for basic services to work (i.e. LLDP link discovery,
ARP proxy. etc.).
- Changed behavior of the flow rule translator and extension selector,
now it allows extension to specify only some of the match parameters
(before extension selectors were expected to describe the whole
match key, i.e. all fields)
- Various renaming to better represent the API
- Various java doc fixes / improvements
