[backend] Implement SSO based on HTTP headers of the reverse proxy (#5107)

[richard-julien]

See #5107.

• Login: add a provider "header" with configuration to map headers
  If the config is available and at least header_email contains a valid email, the user is auto logged by the system

    "header": {
      "strategy": "HeaderStrategy",
      "config": {
        "disabled": false,
        "header_email": "auth_email_address",
        "header_name": "auth_name",
        "header_firstname": "auth_firstname",
        "header_lastname": "auth_lastname",
        "logout_uri": "https://www.filigran.io",
        "groups_management": {
          "groups_header": "auth_groups",
          "groups_splitter": ",",
          "groups_mapping": ["admin:admin", "root:root"]
        },
        "organizations_management": {
          "organizations_header": "auth_institution",
          "organizations_splitter": ",",
          "organizations_mapping": ["test:test"]
        }
      }
    }

• Logout: thats still an open question. For now a logout will auto login back directly
