    hostapd: recognize option "key" as alias for "auth_secret"
    
    The hostapd configuration logic is supposed to accept "option key" as
    legacy alias for "option auth_secret". This particular fallback option
    failed to work though because "key" was not a registered configuration
    variable.
    
    Fix this issue by registering the "key" option as well, similar to the
    existing "server" nad "port" options.
