Windows service: Add support of the Delayed Start option

Currently the service starts in the "Automatic" mode, so there can be conflicts with other services like login service, shared directory mappers, etc. "Automatic (Delayed start)" could resolve this issue by allowing other services to start before Jenkins master/slave starts the initialization.

The change requires https://github.com/kohsuke/winsw/releases/tag/winsw-1.17 at least (not merged into Jenkins core)
