If I store music in CloudDrive, can I play it in somehow? I do not realy like this iTunes syncronization, connect device with cabel, start iTunes, .. too complicate. Can I sync and play music via CloudDrive?
No. Unless you use a specific third-party app that allows this (I don't know of any) then synchronisation of music from a computer to an iOS device with iCloud Drive is not possible. 

However, you may find that iTunes Wi-Fi syncing sufficiently solves the problem you describe of having to physically connect your iOS device to your computer in order to synchronise media.
