Add support to always display login screen (helm#16806)

The current indentation of the OAuth2 configuration block doesn't allow
for extra properties to be added. This allows to enable the new
configuration that will always display the login screen, even though
only one connector is defined.

The default value (disabled) is also added to the values file for
documentation.
