Improve EC2 describe_security_groups performance
The current implementation of EC2 describe_security_groups makes one
query per grantee group rule in _format_security_group. This will
dramatically slow down response time if users make strong use of
grantee group rules.
This patch uses just one DB query to get security groups with joined
grantee_group rules to improve the performance.
Fixes bug 1073024.
