Duplicate all of the IPv4 load balancing test cases for IPv6.
All of these are passing without any changes needed in OVN code, but
this will help ensure that we do not have any IPv6 load balancing
regressions in the future.

Currently the shared umem feature is not supported in libbpf.
The patch removes the refcount check in libbpf to enable use of
shared umem. Also, a umem can be shared by multiple netdevs,
so remove the checking at xsk_bind.

The patch adds support for fetching the datapath's capabilities
from the result of 'check_support()', and write the supported capability
to a new database column, called 'capabilities' under Datapath table.
