Add no sleep functionality

[NikolayJuly]

Build takes a lot of time, we need to add functionality to avoid sleep.
But forth to consider sleep and display sleep are different things, so may be this is not needed of mac not going to sleep with desplay off

Can be done like this:

var assertionID: IOPMAssertionID = 0
        let assertResult = IOPMAssertionCreateWithName(kIOPMAssertionTypeNoDisplaySleep as CFString,
                                                       IOPMAssertionLevel(kIOPMAssertionLevelOn),
                                                       "Long runnign job" as CFString,
                                                       &assertionID)
        defer {
            IOPMAssertionRelease(assertionID)
        }

        logger.info("Requested system not to sleep with result \( assertResult == kIOReturnSuccess ? "success" : "failure" )")
