Add detection and parameter injection

[cfsdes]

Please add a feature that allows it to test the payload on all GET and POST parameters identified in the request.

This is an essential feature to test XSS on a specific page parameter, for example, without having to specify it in the template.

Functionality example:

Target: http://example.com/?parameter_vuln=1

When we specify in the nuclei that we want to test parameters, it will automatically detect that the target parameter is "parameter_vuln" and will inject our payload into it, without having to specify it in the template.
