[Bug 1691902] [NEW] Should not allow security group from other project pass API layer check when booting
Public bug reported:
Currently, the default behavior of neutron when list security groups is:
if you are "admin", response everything we have in the env, and if the
user uses a security group from other project to boot a server, Nova
will show no error in API layer check but error raised in compute layer:
Step1:
get security groups list using admin role:

nce
This inconsistancy is caused by:
In API layer, we checked security groups using
http://git.openstack.org/cgit/openstack/nova/tree/nova/network/security_group/neutron_driver.py#n145
it is a "show" API and since we are using admin context, it will get the response
But in compute layer:
http://git.openstack.org/cgit/openstack/nova/tree/nova/network/neutronv2/api.py#n623
we are getting security group info by "list" API and filtering with instance.project_id and
obviously we cannot get what we want.

This inconsistancy is caused by:
In API layer, we checked security groups using
http://git.openstack.org/cgit/openstack/nova/tree/nova/network/security_group/neutron_driver.py#n145
it is a "show" API and since we are using admin context, it will get the response
But in compute layer:
http://git.openstack.org/cgit/openstack/nova/tree/nova/network/neutronv2/api.py#n623
we are getting security group info by "list" API and filtering with instance.project_id and
obviously we cannot get what we want.
