Bz1127954 amqp default port

I've waffled on this one a bit.  Originally, I thought it would be a good idea to default to assume AMQP over SSL.  However in practice, that's proving to be the wrong choice.

When setting up AMQP to use SSL, several steps are involved including copying ssl certs from the AMQP server over to the ManageIQ appliance.  Defaulting to the SSL AMQP port assumes that the user is going to take these steps.  It's better to assume non-ssl, and then include changing the default AMQP port number
part of the steps for configuring AMQP to use SSL in the appliance.

With this change, the default port value in the AMQP event monitors and the default worker settings assume non-ssl for AMPQ.

I really don't know.  I've seen a little feedback on the AMQP SSL support.  Mostly negative, to be honest.  The main problem being that we require the CN to be set to the AMQP IP Address in the certificate instead of the AMQP hostname.  The general consensus is that no one uses the IP Address in the certificates.

But, since we open all of our connections to EMSes using the IP address, the cert has to match the URL used to open the connection.

Total side issue at this point.  But, might suggest that very few people are actually relying on the AMQP SSL support right now.
