Fix polling ICSHWI-8983

Replaces API polling using setInterval across the application with a hook useSafePolling. Replaces conditional API polling using setTimeout with conditional polling using useSafePolling and watcher components

Also updates NotificationProvider to

• fix bugs (like not being able to clear notifications)
• fix bug in Command job watching where we were using awxJobId property name instead of awxCommandId
• make all context functions stateful (so notifications appear immediately in UI, not just at next poll)

Also fixes some state weirdness in IOCDetailsView -> IOCService

• watchCommand was being called in a weird place
• useOngoingCommand was not memoizing the function causing bad rerenders
• fixed buttonDisabled logic
• fixed bug where UI was locked up with an ongoing command (now we watch and show status of ongoing command instead)
