Good question，if we set dm as a default part for palyground maybe not a good idea，when user issue tiup playground，maybe this should not include start a dm cluster。 What do you think？@GMHDBJD @xhebox
Yes, I don't think it should be included here. And it did not break playground only because PD.Num >= 1 in normal cases...

dmmaster.num defaults 0, pd.num defaults 1, so tiup playground start a tidb cluster default, but I think we should allow user start a dm cluster without tidb/pd/tikv, so here change the logic to allow follow command.
tiup-playground nightly --dm-master 1 --dm-worker 1 --db 0 --kv 0 --pd 0 --tiflash 0

Now we can start a dm cluster without pd, so allow pd to be zero
tiup-playground nightly --dm-master 1 --dm-worker 1 --db 0 --kv 0 --pd 0 --tiflash 0
