SSO via OIDC (Tenant)

[allenzhou101]

Adds SSO via OIDC for a tenant. How it works is as follows:

1. User configures tenant with OIDC
2. In this application, they'll enter the tenant id and hit "Sign in via SSO"
3. Makes a backend request to call SSO start, which returns a URL
4. The client will redirect to the returned url where the user will authenticate with the configured IdP
5. Upon authentication, the user will be redirected back to a server side endpoint where the sso exchange will occur, and an authenticated user will be returned
6. The browser will show a message with a message indicating authentication is successful along with the email of the user
