[ADD] dms_partner_attachment_link: add module

[dmitriypaulov]

This module adds "DMS Attachments" smart button to the partner's form leading to a set of related, stored as attachments DMS files

Which is the difference with https://github.com/OCA/dms/tree/15.0/dms_attachment_link ?

And why not using dms_field for this?

The difference is that dms_attachment_link adds a wizard for files quick creation from records of specific models. This module just adds a shortcut to see partner related files. I hope that is clear, please let me know if I'm wrong

[pedrobaeza]

Well, not really clear the usefulness of this, but it's OK, don't worry.
