[FEATURE REQUEST] httptest strict/require setting

[kalmant]

Is your feature request related to a problem? Please describe.
During testing I expected github.com/kataras/iris/v12/httptest.Response.Status to fail the test immediately if a different status is received. Therefore on subsequent lines I performed some operations that could result in a panic if let's say the response code was not as expected. It turns that it does not fail fast, it simply fails the test. This is because New configures Expect with Reporter: httpexpect.NewAssertReporter(t).

Describe the solution you'd like
I would like to be able to set Reporter to httpexpect.NewRequireReporter(t). I think this could be done by extending Configuration with a new field (e.g. Require bool or Strict bool) and then configuring httpexpect.Config using that value. I'd be happy to contribute this solution.

Describe alternatives you've considered
I have considered copy pasting github.com/kataras/iris/v12/httptest.New and manually setting Reporter to httpexpect.NewRequireReporter(t) (where httpexpect is actually github.com/iris-contrib/httpexpect/v2) by copying httptest.New but I think that's not the right way to go about things.

Additional context
None
