Subject: Exit with success unless the issue was with with tangd itself

    When an HTTP parser error happens, tangd is currently exiting with an
    error status, which may cause trouble in some scenarios [1].

    However, we don't exit with an error in situations where we try requests
    that do not exist, for instance. It makes sense to only exit with an
    error when the error was with tangd itself, e.g.: when we are unable to
    read the directory with the keys, not when the actual HTTP operation
    does not succeed for some reason.
