Security Groups: Add Rule dialog does not specify the option to create an IPv6 rule.

[Nir Magnezi]

Description of problem:
=======================
The Add Rule dialog does not allow you to specify the 'Ether Type' for the rule.
Instead, It auto detects if the CIDR is IPv4 or IPv6 and creates the rule accordingly.
Having that approach, I Would suggest that the IPv4/IPv6 auto-detection will be better reflected to the user.

Currently:
a. The default CIDR is: 0.0.0.0/0
b. The CIDR Field help: Classless Inter-Domain Routing (e.g 192.168.0.0/24)
c. The IPv6 is not described as valid input in the Dialog Description.

Steps to Reproduce:
===================
See the dialog at: http://<FQDN>/project/access_and_security/security_groups/<sec_group_id>/add_rule/

Hi

You can't edit "Ether Type" in horizon . so you options is always IPV4, No IPv6 options via Horizon .(liberty and Kilo)

Check CLI that support it, please reopen the bug

Thanks
