Subject: [PATCH] Allow pulsar_tool_env.sh PULSAR_MEM & PULSAR_GC to be
 Overridden

The pulsar_tool_env.sh sets the PULSAR_MEM and PULSAR_GC environment variables without allowing them to be overridden.
This change keps the default values but allows PULSAR_MEM & PULSAR_GC to be overridden which aligns with the
pulsar_env.sh file. This allows adjustments to be made to the memory settings when more memory is needed.
