Creates a {@link ResponseAwareMatcher} that extracts the given path from the response and
wraps it in a {@link org.hamcrest.Matchers#equalTo(Object)} matcher. This is useful if you have a resource that e.g. returns the given JSON:
<pre>
{
"userId" : "my-id",
"href" : "http://localhost:8080/my-id"
}
</pre>
you can then test it like this:
<pre>
get("/x").then().body("href", containsPath("userId"));
</pre>

@param path The path to check
@return A {@link ResponseAwareMatcher}
