User can cancel a migration in progress

[serenamarie125]

User can cancel a migration. Need to finalize the requirements here:

• is cancel action only enabled/available for migrations in progress
• cancel confirmation should be shown

[serenamarie125]

@bzwei do we have existing API support for this?

[vconzola]

@serenamarie125 Where did this one come from? It's definitely good to have, I just don't see a Trello card for it. Another big requirements question is are we cancelling a whole plan or just individual migrations? Whole plan is more difficult because we need to take into account what we do with individual migrations that can be in different states - gets messy.

@vconzola Brett said it was an ask for sprint 9

[bzwei]

We don't have existing API for canceling, nor do we have backend support. It will be a feature that requires a lot of effort.

Thanks @bzwei - FYI @bthurber if this is a need, can you chat with Greg B in priority? Taking off our sprint9 plans

Preliminary API spec for cancel from Fabien is here:

We can start prototyping this next...

Starting on this while I wait for review on #467 to wrap up #399 .

[mturley]

My PR for this will go out today. I dropped the ball on finishing #399 this sprint because it needs another API call. But this I can have done today.

[mturley]

@JPrause sorry for the delay. The backend PR for this issue is now merged. The frontend PR will be up shortly and merged early next week (only because it's late Friday).

[bzwei]

@mturley please use this API call ManageIQ/manageiq-api#421

[mturley]

Sounds good, thanks @bzwei. This is my top priority.

[mturley]

This will now be done in #511, my original entire-plan cancel PR was, well, cancelled.
