provider/aws: Support ec2-classic and vpc in beanstalk recurring plans. (#6491)

* provider/aws: Support ec2-classic and vpc

Fix Elastic Beanstalk recurring plans when additional security groups
are supplied. In the previous version, only non-default vpc security
groups would be handled by dropGeneratedSecurityGroup.
