This is needed so that we can add OS version constraints in Swarmkit, which does require the engine to report its host's OS version (see https://github.com/docker/swarmkit/issues/2770). The OS version is parsed from the `os-release` file on Linux, and from the `ReleaseId` string value of the `SOFTWARE\Microsoft\Windows NT\CurrentVersion` registry key on Windows. Added unit tests when possible, as well as Prometheus metrics. Signed-off-by: Jean Rouge <rougej+github@gmail.com>
