    Hi @StephanEwen , with the help of your `MemorySize` (sub task of 
FLINK-6469)，I finished the remained work, replaced the old memory config (in 
code、config file and shell script) with the memory size. 
    
    For the config item in `conf/flink-conf.yaml`, retained but deprecated the 
config key `jobmanager.heap.mb` , `taskmanager.heap.mb` and introduced 
`jobmanager.heap.size`, `taskmanager.heap.size` with the unit `m`. 
    
    Would you please review this PR, thanks!
