Issue tracker migration

OSS-Fuzz will be changing issue trackers later this week (we must do this and do not have a choice).
We expect to do this on Thursday, September 19th.
Existing issue links will be redirected to the new issue tracker.
We will send out more details in an email to everyone in auto_ccs, vendor_ccs and primary_contacts later this week.
There will be some downtime (probably around 8 hours).
The issue tracker will be similar to chrome's new issue tracker: https://issues.chromium.org/

The issue describes an OSS-Fuzz issue-tracker migration but names no repository files, tests, or implementation entry points. Read the migration details and linked tracker information first; the issue does not define a code change or a concrete completion criterion for a contributor.
