This is the umbrella ticket of [FLIP-141: Intra-Slot Managed Memory
Sharing|https://cwiki.apache.org/confluence/display/FLINK/FLIP-141%3A+Intra-Slot+Managed+Memory+Sharing].
[FLIP-53|https://cwiki.apache.org/confluence/display/FLINK/FLIP-53%3A+Fine+Grained+Operator+Resource+Management]
introduced a fraction based approach for sharing managed memory within a slot.
This approach needs to be extended as python operators, which also use managed
memory, are introduced. This FLIP proposes a design for extending intra-slot
managed memory sharing for python operators and other potential future managed
memory use cases.
