Bug 1652491: filter security group list based on provider

Fixes https://bugzilla.redhat.com/show_bug.cgi?id=1652491

For setting the remote security group for security group
rules, the dropdown included *all* security groups, including
those for other providers. This commit filters the list
to only show security groups for the current provider.
