CVE-2022-39229: Add test for username/login field conflict · grafana/grafana@5644758

Grafana is an open source data visualization platform for metrics, logs, and traces. Versions prior to 9.1.8 and 8.5.14 allow one user to block another user’s login attempt by registering someone else’e email address as a username. A Grafana user’s username and email address are unique fields, that means no other user can have the same username or email address as another user. A user can have an email address as a username. However, the login system allows users to log in with either username or email address. Since Grafana allows a user to log in with either their username or email address, this creates an usual behavior where user_1 can register with one email address and user_2 can register their username as user_1’s email address. This prevents user_1 logging into the application since user_1's password won’t match with user_2's email address. Versions 9.1.8 and 8.5.14 contain a patch. There are no workarounds for this issue.
