sysinfo.NumCPU returns the number of CPUs which are currently online, which involves some syscalls and parsing on Windows. Change the code to only retrieve this information when needed, and memoize the result to prevent calling this function multiple times. Ideally, we'd obtain this information from daemon.RawSysInfo(), but that uses a sync.Once, which could return outdated information.

Deprecate in favor of `runtime.NumCPU` as the behavior is the same now. Signed-off-by: Paweł Gronowski <pawel.gronowski@docker.com> (cherry picked from commit 3db72b2) Signed-off-by: Sebastiaan van Stijn <github@gone.nl>
