Dimitris Athanasiou 0b6ac175da [ML] Check datafeed can be assigned before creating task (elastic/x-pack-elasticsearch#1027)
When a datafeed task is created but it cannot be assigned the task
has a null status. This means _stats report it as stopped, however
deleting it fails. In addition, it's a better experience to error
the start datafeed request all together and give the user the chance
to fix his data indices.

This change fails a datafeed-start if it cannot be assigned.
