[strict-mode] unknown config directive: max-worker-lifetime-delta

Hi there,

Undocumented option max-worker-lifetime-delta triggers error unknown config directive: worker-lifetime-delta when using uSWGI in strict mode.

max-worker-lifetime-delta was committed to master in 2.0.19 and is still present in the latest master.

The strict mode documentation says:

while having the freedom of defining custom options in uWSGI config files is a handy features, sometimes typos will bring you lot of headaches.

Adding –strict to your instance options will instruct uWSGI config parser to raise an error when not-available options have been specified.

I don't know why this uWSGI-defined option is returning an error as if it were a user-defined option.

Any news on this one? The max-requests-delta option behaves alike in version 2.0.21. See: #1488
