Investigate (and if available, implement) better Jira interface for link request

Currently, we use 'type' in Jira to show link request in SURFconext dashboard. We find that sometimes SURF employees have a good reason to change the Jira ticket type to for instance 'sub-ticket'. This however overwrites the type 'SSI Link Invitation'. We wonder whether there is a better mechanism that does not have this drawback. Maybe use Jira labels? Adding a custom field feels like a risk (better stay with out of the box Jira functionality as far as possible?)

Decided together with HeBe, RaTe and ThKi that we - for now - do not tinker with the Jira interface. Moved to icebox (Okke Harsta - Oct 8, 2020)
