Request: Add a comment field to sponsors

[scoutb-cogapp]

Additional comment field when setting up sponsors

As a chapter organiser, I would like to store additional information for host/sponsor contacts. Right now, we can store a first name, a last name, and an email address. I would like to be able to save a note for each contact too.
This can be used for example to note who the main contact is, what their job title in the company is etc.

• As discussed in Slack, this field should be called "contact comment" to remain versatile but make it clear this is not a comment about the host in general
