"Dump scheduler logs"

• Tries to link to http://localhost:8443/ws/v1/cluster/scheduler/logs 
  • Correct link should be http://localhost:8443/gateway/test/yarn/ws/v1/cluster/scheduler/logs
• Root cause
  • Missing rewrite rule for /ws/v1/*
  • https://github.com/apache/knox/blob/master/gateway-service-definitions/src/main/resources/services/yarnui/2.7.0/rewrite.xml#L26
