  Fix request factory used with TestRestTemplate withBasicAuth

Fixes gh-15982

This commit updates the behavior of withBasicAuth on TestRestTemplate
by trying to use the same request factory type as the underlying restTemplate.
If creation of a new instance of the configured request factory class fails,
it falls back to the `ClientHttpRequestFactorySupplier`.

Prior to this commit, exceptions nested in
`NestedServletExceptions` would not be recorded by the
`WebMvcMetricsFilter`. This commit ensures that exceptions
happening downstream (e.g. happening while writing the response
body itself) are properly recorded.
