Description

Datanode may fail to start:

ERROR org.apache.hadoop.ozone.HddsDatanodeService: Exception in HddsDatanodeService.
java.lang.NullPointerException
	at org.apache.hadoop.ozone.container.ec.reconstruction.TokenHelper.<init>(TokenHelper.java:68)
	at org.apache.hadoop.ozone.container.ec.reconstruction.ECReconstructionCoordinator.<init>(ECReconstructionCoordinator.java:119)
	at org.apache.hadoop.ozone.container.common.statemachine.DatanodeStateMachine.<init>(DatanodeStateMachine.java:185)
	at org.apache.hadoop.ozone.HddsDatanodeService.start(HddsDatanodeService.java:279)

if misconfigured:

  <property>
    <name>hdds.block.token.enabled</name>
    <value>true</value>
  </property>
  <property>
    <name>hdds.container.token.enabled</name>
    <value>true</value>
  </property>
  <property>
    <name>ozone.security.enabled</name>
    <value>false</value>
  </property>

TokenHelper should check for this case.
