Is your feature request related to a problem? Please describe.
Currently to configure endpoints related to authentication, use has to manually edit a property file and fill in all the endpoints

authorizeEndpoint=https://accounts.asgardeo.io/t/<yourTenantDomain>/oauth2/authorize
logoutEndpoint=https://accounts.asgardeo.io/t/<yourTenantDomain>/oidc/logout
tokenEndpoint=https://accounts.asgardeo.io/t/<yourTenantDomain>/oauth2/token
issuer=https://accounts.asgardeo.io/t/<yourTenantDomain>/oauth2/token
jwksEndpoint=https://accounts.asgardeo.io/t/<yourTenantDomain>/oauth2/jwks

Describe the solution you would prefer
Instead of all these input we should be able to discovery all the endpoints required simply using the issuer value using OIDC discovery
