      Description

      YARN-8080 implements restart capabilities for service component instances. YARN service components should add an option to disallow flexing to support workloads which are essentially batch/iterative jobs which terminate with restart_policy=NEVER/ON_FAILURE. This could be disabled by default for components where restart_policy=NEVER/ON_FAILURE and enabled by default when restart_policy=ALWAYS(which is the default restart_policy) unless explicitly set at the service spec.

      The option could be exposed as part of the component spec as "allow_flexing".
