Fixes CodeCeption tests

[wisyhambolu]

• Fixes https://github.com/humanmade/product-dev/issues/1525, the issue were originally failing due to rate limiting on the NGINX server on local server and was returning 429 errors. This fix adds waits at different times to avoid the rate limiting.

Well done for finding this.
Is there a possibility to reduce/remove the rate limit on nginx? Otherwise, I think this means all future tests (including ones clients write) will have to incorporate these delays.
Alternatively, do the delays need to be so long?
Tests that take too long to run tend not to get used.

Change looks fine. I agree re. long tests though, I think it's worth removing rate limiting in Local Server, it is not useful at all.

We can override the rate limits in the nginx container per https://github.com/humanmade/docker-wordpress-nginx/blob/master/docker-entrypoint.d/config-replacements.sh, we'd need to just define the env vars in https://github.com/humanmade/altis-local-server/blob/master/inc/composer/class-docker-compose-generator.php#L337

Thanks for the feedback everyone, I'll create a PR to override the rate limits in the nginx container.
