api-ref: describe which protocols are enabled for stateless SG

Browse Source 
This behavior matches what ML2/OVS implementation does and what we
intend to implement for ML2/OVN. More than that, a decision was made
during vPTG to make the behavior part of api-ref to facilitate
cross-backend consistency.

@ -39,6 +39,14 @@ The existing security groups will all be considered as stateful. Update of the
``stateful`` attribute is allowed when there is no port associated with the
security group.
Regardless of rules defined for a stateless security group, the following
protocols are expected to work: ARP, DHCP, IPv6 SLAAC / DHCPv6 stateless
address configuration, IPv6 Router and Neighbour Discovery.
Note: metadata service is not enabled by default. If your workload requires
metadata for configuration, make sure to create a security group rule that
would allow HTTP replies from the metadata service IP address / port pair.
