Fixes #6455

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''"

* This enable a user to configure uri in get_xml function

Also fixed a bug in which the state parameter was marked as a 'bool'
type, which was breaking execution of the module.

Fixes #6543

It's a separate parameter so updated docs and set it as mutually exclusive param.
Also due to an array construction typo it was not working in any situation (ufw LOGLEVEL was passed to cmd instead of ufw logging LOGLEVEL).

Also fixed doc and parameters parsing typo ("choises" should be "choices")

This PR introduces support for a lldp module.

lldpd is similar to CDP and can return useful details about a server's network like ports, switches, and VLANs.

This module uses a2enmod or a2dismod to enable or disable
Apache2 modules.
