Future of the Management Representative

I would like to know how an organization should deal with the Management Representative being non-mandatory in 2015 version? What's the suggestion?

The fact that the management representative is not mandatory doesn't mean it is forbidden, so if your organization find this role useful, you should keep it. This person is usually the most familiar with the standard and the system, so keeping management representative as a coordinator of all QMS related activities can be beneficial for the organization.

And I also want to know, if I want to be a consultant for implementing ISO 9001:2015 standard requirements within an organization, do I need only the standard knowledge or there are other formal training, certificates or requirements needed?

No additional training and certificates are requi red. For consultants, the best measure of their success and competence is the certification audit. If your client fails the certification audit, they won't care about your certificates and also if they get the certificate. On the other hand, this is a way to demonstrate to your clients that you are competent and able to implement the standard. Usually consultants take courses for Lead Auditor and Lead Implementer, but the key is to build up your reference list because it will say much more that the certificates themselves.
