max-requests-delta and strict mode

[philtay]

It looks like that the max-requests-delta can't be used in strict mode.
Steps to reproduce:

1. Create foo.ini:

[uwsgi]
strict = true
max-requests-delta = 100

2. Start uWSGI:

$ uwsgi --ini foo.ini

Result:

[uWSGI] getting INI configuration from foo.ini
[strict-mode] unknown config directive: max-requests-delta

uWSGI version 2.0.14

[unbit]

max-requests-delta is a 2.1 option

I am pretty sure, this has been backported, but strict mode still complains about max-requests-delta in 2.0.21. More surprisingly, the even newer option max-worker-lifetime-delta is allowed in strict mode 😅

@unbit I can find no release for 2.1. The latest version is 2.0.22. The problem still exists in 2.0.21
