Feature: Safely shutdown cloudstack

[davidjumani]

Description

Adds the feature to safely shutdown CloudStack It does the following :

• Prevents new Async jobs from being added
• Waits for existing jobs to finish before shutting down

Contains 4 new apis :

• TriggerShutdown - Prevents new jobs and shuts down once all pending jobs are completed
• ReadyForShutdown - Returns whether a shutdown has been triggered and the no of pending jobs
• PrepareForShutdown - Prevents new jobs from being added but does not shutdown when there are zero pending jobs : Useful when admin changes are required in ACS which can impact operations
• CancelShutdown - Cancel a shutdown if possible

[DaanHoogland]

looks generally good. A functional question though, there is a UI component, but will the API let all clustered MS shutdown? (I didn´t see code for that) It seems only the MS that happens to handle the API will shut down.

@davidjumani can you explain this?

@davidjumani can you explain this?

That's right, it only shuts down the MS which handles the request
