Linking collaborators project owner flow

[niraymak]

Is your feature request related to a problem? Please describe.
We are currently working on a flow where DeX users can link theirselves to a collaborator.

Describe the solution you'd like
We would like a different flow where a project creator can link users as collaborators while creating a project (in the wizard) and in the edit project page. The current implementation requires the creator to know the users emailaddress. The collaborator will receive an email which contains a URL that can be used to accept the 'collaborator link request'.

Production URL

Additional context
Keep in mind that the implementation is GDPR proof.
