Implement Rate Limit Feature

[v4resk]

Hello,

I'd like to propose the implementation of a rate limiting feature. It would be very useful for applications that use rate limiting or have low bandwidth.

Best regards,

Hi,

I just implemented this on my repo (see here) and created a pull request (see here).

You can use -rt or --rate and pass a positive integer to it, which is the maximum number of requests per minute. Example to send a maximum of 30 requests:
python3 jwt_tool.py -r req.txt -t 'https://google.com' -np -M at --rate 30

I didn't implement the option per second because the script is already running ~1 request per sec. Thus the need for rate limiting would be to fall under 1 RPS and use rates like 0.2478 requests per seconds, which doesn't seem supported by the library I used.
