Given a list of security groups and a vpc_id, convert_to_group_ids will
    convert all list items in the given list to security group ids.

    CLI example::

        salt myminion boto_secgroup.convert_to_group_ids mysecgroup vpc-89yhh7h

def convert_to_group_ids(groups, vpc_id=None, vpc_name=None, region=None, key=None,
                         keyid=None, profile=None):
