b2b9e22b24 [CreateTable] Check backend disk has available capacity by storage medium before create table (#3519) 
Currently we choose BE random without check disk is available, 
the create table will failed until create tablet task is sent to BE
and BE will check is there has available capacity to create tablet.
So check backend disk available by storage medium will reduce unnecessary RPC call.
