Setting java memory options via kubernetes yaml

[#1]

In nifi, we set java memory configurations(Xms, Xmx) in bootstrap.conf.

Is it possible to set it via kubernetes yaml?

I tried with 'args' or with env variable JDK_JAVA_OPTIONS/JAVA_TOOL_OPTIONS , but none works.

Can you please try these two 

NIFI_JVM_HEAP_INIT

NIFI_JVM_HEAP_MAX

Thank you
