> Nodetool and other bash startup scripts load cassandra-env.sh variables including MAX_HEAP_SIZE
as part of CASSANDRA-10679.  If cassandra-env.sh has MAX_HEAP_SIZE set to any value the default
heap size needed for the cassandra tool to run is overridden.  
> This is a problem if the using a large heap in C* i.e. 16-32G due to each instance of
nodetool or other tool will allocate large heap regardless of need and could exceed the total
RAM available on the system.
> Patch removes the check for MAX_HEAP_SIZE being set and uses the default heap size needed
for each tool.
