Comment 4 for bug 1144426

In my understanding, there is no such consensus.

We need to consider both source_ip_prefix and source_group_id.

Regarding source_ip_prefix, there is no problem even when we drop "source_".

On the other hand, the situation is different in the case of source_group_id.
"group_id" is confusing since we have "security_group_id" attribute.
Thus it would be better to have some prefix which can be used for ingress and egress.
In the mail two or three months ago, I proposed "remote_" as a prefix.

There are some options:
- source_ip_prefix -> ip_prefix / cidr / remote_ip_prefix / remote_cidr ?
- source_group_id -> remote_group_id ?

Is there any other better prefix?
