Allow designation of Primary Contact at the Client Level

[er4z0r]

Is your feature request related to a problem? Please describe.
We currently have the ability to assign multiple contacts to a project and mark one of them as primary contact. I'd like to have this feature on the client level as well.

Describe the solution you'd like
What it'd like is a flag on a client contact that allows to designate them as the primary conact for this client.

Describe alternatives you've considered
Alternatively I could imagine a more versatile solution by adding a multi-valued attribute 'roles' that allows us to add specific roles to a contact. I'd be totally fine with a flag.

Additional context
The main reason for this is that while I know about and use the project contacts feature, most of my colleagues don't. As a result I've had to resort to using a custom jinja filter to find the designated contact/recipient of the report. Currently it relies on a specific word being present in the description of a client's point of contact. It feels like having a simple way designate somebody as report recipient would improve this.

We will look into this. It shouldn't be a major lift.
