Fix custom url redirection issue

[sandushi]

Purpose

• To fix the issue of not redirecting to configured custom urls
• When the tenant qualified urls are enabled, the configured custom urls are not honored.
• To fix that issue, we introduced v2 configurations to add the custom urls and when tenant qualified urls config is enabled, we checked on the v2 cobfigurations and redirect to those configured urls.
• The customers needs to add the customized urls inside the v2 authentication endpoints.

[authentication.endpoints.v2]
login_url= "<URL>"
retry_url= "<URL>"
