Tracking support requests

Currently there is no streamlined process to track our incoming support requests. Support request mails come through nugetcore alias and the primary on call person addresses those emails. Sometimes, these issues fall through the cracks and aren't resolved. In order to better track and resolve support requests we should start tracking them on NuGet Gallery. When a team member logs in through the admin alias, he/she can view a simple dashboard similar to incidents on Pagerduty. There can be one entry for each of the support request with an ability to resolve/ reassign or reactivate the issue. As soon as a request comes in an entry is created in Active state. Similar to Pagerduty, the gallery can send mails whenever there are Active requests. The on-call person needs to act on these requests and mark it as Resolved in the gallery. Pagerduty APIs can be used to automatically assign issues to the primary on-call person.
