The Rhsm object requires an AnsibleModule but it isn't created with an argument_spec and fails. Since the rhn.module is set directly after, setting None for the required argument of Rhsm fixes the module.
While the [boto docs](https://github.com/boto/boto/blob/develop/boto/rds/__init__.py#L253) make it seem like the default value of `port` is changed depending on the engine chosen, AFAICT from looking at the code the default value is never changed from 3306.
I think the docs are intended to be read as "the default value used by <engine> is <port> so you should change `port` to that value".
If you don't specify the port value and chose the database engine as PostgreSQL you'll end up with a PostgreSQL instance running on port 3306.
The mysqldb Ansible module will fail if the state specified is import or dump with a '1045: Access Denied' mysql error for complex passwords.
This is caused by the extra quote around the '--password' argument to mysqldump, as pipes.quotes already quotes the password string.
>>> "--password='%s'" % pipes.quote('simple')
"--password='simple'"
>>> "--password='%s'" % pipes.quote('c0mplexp@ssword!')
"--password=''c0mplexp@ssword!''"
>>> "--password='%s'" % pipes.quote('password with space')
"--password=''password with space''"
Without the `subnet` parameter supplied there's an error `msg: Parameter vpc_security_groups invalid for create command`. (This might be a bug?)
If the VPC security group name rather than ID is supplied there's an error: `msg: Invalid security group , groupId= <some group name>, groupName=.` (Accepting a group name might be a feature enhancement.)
In my case I set the subnet as `default` and used `register` to get the result of the security group creation section and just referred to its `group_id` property.
