Adding Http Modules Docs

[Yashvendra]

Adding auxiliary/scanner/http/http_put and auxiliary/scanner/http/scraper documentation.

@bcoles Thanks for the help!

Modules should have an ## Options heading which defines the module options.

• Template
• Examples

For the http_put module, you should also describe the different module ACTION values.

Also, the ## Scenarios section should offer vaguely realistic scenarios. For example, for the scraper module, although the PATTERN default is reasonable, it would make sense to show setting the PATTERN anyway, ie:

set PATTERN <title>(.*)</title>

I updated the doc accordingly but one simple question, I should now just replace the old docs with the new docs on my local repo while remaining at http_doc branch and simply just push it again right?

If you planned on updating this PR, you should be editing the docs while in the http_doc branch.
After editing the docs commit the changes and then push the http_doc branch.

If you modified the docs outside of the http_doc branch then copy the docs to the http_doc branch, commit, and push the http_doc branch.

Consider adding a line here:

Set `ACTION` to either `PUT` or `DELETE`. (default: `PUT`)

Release Notes

Documentation has been added for the http_put module and scraper auxiliary scanner modules.

This is missing a ## Options section, where you'd mention the PATTERN and call out the default instead of putting it in the scenarios section.
