launch instance modal volume quota check

[Cindy Lu]

When you select an 'Instance Boot Source' that will create a new volume (i.e. Boot from Volume Snapshot) and press the submit button, there should be a front-end check to check the current number of volumes.

Because if it already reached the quota level, it will error out and give you generic error message: "No valid host was found." - which is not helpful.

Number of instances is validated on the modal, I think the volumes should be as well, if new volumes are created.

So, the problem is with the error message right?

[Cindy Lu (clu-m)]

Yes, Facundo. validation on the modal form and then show error there.

It would also be nice to add the volume bar graph under Project Limits on the right in order to make this clear in advance.
