implement support to alter urls ( ex: `qsreplace` )

[tarunKoyalwar]

Proposed Changed

• alterx now has full support for generating subdomains/urls by using patterns with clusterbomb . It should also support Alteration
• Alteration would be a seperate feature similar to qsreplace

// Example
$ cat urls.txt. | alterx -a "{{qvalue}}=xss.txt". // replace all query values in urls with xss payloads
$ cat urls.txt. | alterx -a "{{qvalue}}=sqli.txt" // replace all query values in urls with sqli payloads

• Support replacing only 1 payload at once

$ cat urls.txt. | alterx -r "{{qvalue}}=xss.txt"  --alter-once // should not replace all parameters

Anything else

• Config file ? Format ? cc: @ehsandeep
