Additional operator edge case fixes

[ikreymer]

Fix a few edge-case situations:

• Restart evicted pods that have reached the terminal Failed state with reason Evicted, by just recreating them. These pods will not be automatically retried, so need to be recreated (usually happens due to memory pressure from the node)
• Don't treat containers in ContainerCreating as running, even though this state is usually quick, its possible for containers to get stuck there, and will improve accuracy of exec seconds tracking.
• Consolidate state transition for running states, either sets to running or to pending-wait/generate-wacz/upload-wacz and allows changing from to either of these states from each other or waiting_capacity
