Limit body buffering to avoid resource exhaustion

[Enrico204]

This PR implement a limit for body buffering in order to avoid resource exhaustion using a very large body (see #7). The default limit is 10MB (which should be enough for non-uploads requests), but it's configurable.

Awesome, although you should specify the new option in the .traefik,yaml file

traefik-modsecurity-plugin/.traefik.yml

Lines 8 to 9 in 19cdb47

	testData:
	ModsecurityUrl: http://waf:80

And probably add a documentation about it, the default value and the reason inside the readme.

Thank you very much for this!

Done! 👍
(this is the first time I see the code for a traefik plugin)

I took the liberty of adding a new section in the README, named "Configuration", showing both the configuration parameters. I also added the configuration for maxBodySize inside the docker-compose files and the traefik YAML.

Let me know if you have any comment :-)
