How to deal with the E-Mail forwarding service being in limbo

[andk]

Tentative collection of measures we need to get into effect today (day one without email forwarding)

• global idea on this changeset
  • introduce a global variable $cpan_dot_org_mail_forwarding_ok = 0;
  • all parts of the user interface that rely on a working
    cpan.org-mail-forwarding-service must be modified in a way that
    makes it clear to the user that the service is at the moment not
    available. Bike shedding follows:
    • text referring to these features should get a consistent markup:
      maybe start the text parts with a not too intrusive "under
      construction" symbol and change the foreground and background
      color to a unique style not used elsewhere in the user interface
    • any markup is allowed here as long as it is not misleading the
      user
  • the resulting code should be switchable back to the currently
    visible userinterface as soon as we change the global variable to a
    true value.
• concrete changes
  • (conditionally on $cpan_dot_org_mail_forwarding_ok = 0) before the
    sentence "The email address .... should be configured to forward"
    insert in bold "🚧 The mail forwarding service is currently not
    available. Changes here will only take effect when the service can
    be started up again. -- "
