    @StephanEwen 
    for the `taskmanager.memory.segment-size` because of it's default unit is `byte`, so whether
there is a unit or not, the behavior is consistent.
    
    So we just need to handle `taskmanager.memory.size`

> Currently, memory sizes are configured by pure numbers, the interpretation is different
from configuration parameter to parameter.
> For example, heap sizes are configured in megabytes, network buffer memory is configured
in bytes, alignment thresholds are configured in bytes.
> I propose to configure all memory parameters the same way, with units similar to time.
The JVM itself configured heap size similarly: {{Xmx5g}} or {{Xmx2000m}}.

> 10000  -> bytes
> 10 kb
> 64 mb
> 1 gb
> ...
> {code}
