ECMP load balance configuration agent changes.

ECMP load balance parameters can be configured at global, vn and interface level.
Priority (highest to lowest)- Interface, VN, Global.
This config is stored in path. When path is exported to controller, fields in
load-balance-fields are populated using the same. Agent currently provides field
based hashing only. So every controller message will have load-balance-type set
to field-hash. Similarly reflected routes from CN will be used to extract fields
to be used for hashing and populated in respective path.
Agent by default will use all fields.
