Add Live Migrate actions to the task queue.

[mansam]

Use the task queue for Live Migrate instead of calling the action directly from the UI.

Depends on ManageIQ/manageiq#13491 which contains the backend changes.

This is what I get when I run the instance migration on a OpenStack cloud provider:

No route matches {:action=>"wait_for_task", :controller=>"vm", ...} [vm/live_migrate_vm]

[mzazrivec]

I'm having trouble understanding the above logic. If task_id is not integer, we're gonna render a flash error
telling that a task with id task_id failed? What will task_id contain at this point? Will it really be the task's id?
Then it would be an integer, right? But at the same time it wouldn't pass the unless task_id.kind_of?(Integer) condition.

[mansam]

You are of course right, the id in the flash error is mistaken.

[mansam]

I don't get that route problem. The route is defined in this patch, and when I run it locally the requests to wait_for_task succeed.

[mzazrivec]

The routing error I shown above will show when you navigate to OpenStack Cloud Provider ->
its Instances, and from the list view (i.e. not on the instance summary page) you'll select an Instance
and run the migration.

[mansam]

Ah, I see. Fix incoming.
