Description

Currently, MemorySize and Duration ConfigOption doesn't support to parse -1 or -1s.

java.lang.NumberFormatException: text does not start with a number
	at org.apache.flink.configuration.MemorySize.parseBytes(MemorySize.java:294)

That makes us can't to use -1 as a disabled value, and have to use 0 which may confuse users at some senarios.

There is some discussion around this topic in :https://github.com/apache/flink/pull/12536#discussion_r438019632
