feature request - allow for an array of customizers

Customizing the wiremock via the annotation to a separate WiremockCustomizer is really awesome and clean. Similar to #8 I'd like to mock several apis from different downstream services in my wiremock. For readability, I'd like to group by configuration into different customizers. Would it make sense to make have ```@Wiremock``` take customizers as an array and serially customize the wiremock?
