Prior this patch OVN Octavia provider driver used
default 5-tuple-hash algorithm which is pretty similar to
SOURCE_IP_PORT.
Unfornutelly because of the bug described here [1] it
was not clear how 5-tuple-hash works and some inconsistencies
between kernel and user space implementations were found.
OVN recently added support for selective fields in OVN LB, to
explicitly define what fields are being hashed to tackle this problem.
This commit adds support for that kind of hashing. If installation
of OVN on which OVN Octavia provider is running doesn't support
selective fields - it will use old behavior.
