API Extension timeout is configurable

The maximum time the commercetools platform waits for a response from an API Extension is now configurable. The maximum timeout is still limited to 2000 ms. This limit can be increased per project after we review the performance impact. Please contact Support via the Support Portal and provide the region, project key and use case.

• [API] Added timeoutInMs to Extension and ExtensionDraft.
