Quota message wrong for multiple instances

[Stanislaw Pitucha]

Message for exceeded quota is wrong when spawning multiple instances over nova api. When trying to spawn 10 instances, I got back:

ERROR: Quota exceeded for instances: Requested 1, but already used 31 of 40 instances (HTTP 413)

It should be "Requested 10, but...." in this case.

    Fix the multi-instance quota message

    Make sure that when spawning multiple instance, the quota exceeded
    error still makes sense. Instead of reporting min_count (1) as the
    requested number, report "between min_count and max_count".

    Fixes bug 1211347
