Add support for specifying the HTTP method

[ecampidoglio]

Generally speaking, it's better to use specialized arguments to create the right kind of request rather than manually specifying the HTTP method.

This guideline is clearly stated in curl's man page:

Normally you don't need this option. All sorts of GET, HEAD, POST and PUT requests are rather invoked by using dedicated command line options.

Nonetheless, there may be situations where a remote endpoint supports a different method than the one chosen by a given curl option.

For example, when you upload a file to an HTTP endpoint using the -T parameter, curl will by default issue a PUT request. Now, that won't work if the endpoint only supports POST. In those situations, you must be able to specify the HTTP method using the -X option:

curl -X POST -T file.txt http://host/path

It would be nice if CurlSettings supported the -X --request option directly.
