Description of problem: Currently for EvictionStrategy, we support the values "None", "LiveMigrate", "LiveMigrateIfPossible" and "External". Here a value of "None" would cause an eviction. For "WorkloadUpdateMethod" we can pass either "Evict" or "LiveMigrate" and to disable it we pass [] - these are clear to understand. We should support passing an "Evict" instead of "None" for EvictionStrategy, for ease of understanding.
