• feature request

What is the current behavior?

The report only attach url, method, headers, body, cookies of a request but does not attach the form params.

https://github.com/allure-framework/allure-java/blob/master/allure-rest-assured/src/main/java/io/qameta/allure/restassured/AllureRestAssured.java#L80

What is the expected behavior?

The report should display form params as well or should have capability to customize what all things of a request we want in the report

What is the motivation / use case for changing the behavior?

My request has form params and I would like them to be displayed in report as part of the request attachment.

                  given()
			.header("content-type", "valid content type")
			.formParam("abcd", "abcd")
			.formParam("xyz", "xyz")
