Enable/Disable Items with authentification headers

[knom]

Hey there,
I'm trying to reinvigorate #1304 by doing the the changes requested @KodeStar and @albinmedoc.

Use case:

• the Heimdall server is located behind a login page provides by a SSO service like authelia or Keycloak
• You want to define common services only once and share them between users enabled by the roles they're assigned to

New feature when enabled:
*The Heimdall settings (order of items, application list, tag list, settings) are only visible for users with role admin.

• For every application and tag the new field Authentification role is added. This filed contains the role to witch the application or tag is displayed.
• Applications and tags are only displayed when the logged in user is member of the configured role.

Configuration:

• The feature can be enabled/disabled in the env file with AUTH_ROLES_ENABLE.
• It is possible to configure the header containg the roles by AUTH_ROLES_HEADER and AUTH_ROLES_HTTP_HEADER.
• The role to enable the Heimdall settings can be set wit AUTH_ROLES_ADMIN.

@KodeStar:
Please let me know if anything else is required - as I really would like to ship this (for my own sake - to use with my AUTHENTIK instance).

Thanks, knom.
