Suspendable ServerRequestFilter in Resteasy Reactive

Description

The following return types are currently possible in Resteasy Reactive Filters (@ServerRequestFilter): void, Response, RestResponse, Optional<Response>, Optional<RestResponse>, Uni <Void>, Uni<RestResponse> or Uni <Response>.

Please add support for suspendable filters (Kotlin Coroutines).

Example

class Filters {

    @ServerRequestFilter(preMatching = true)
    suspend fun preMatchingFilter(requestContext: ContainerRequestContext): RestResponse<String>? {
        return if (requestContext.method == HttpMethod.GET) {
            RestResponse.ok("GET", MediaType.TEXT_PLAIN_TYPE)
        } else {
            null
        }
    }
}

Yeah, we can certainly do that. But it will likely be a 2.3 enhancement, not a 2.2 one
