Cinder consistency group returning generic error message

[David Rosales]

When trying to create a consistency group with the quota reached already, the error raised to the user is the generic "ERROR: The server has either erred or is incapable of performing the requested operation. (HTTP 500)" message. The true reason can be found in the logs.

OverQuota: Quota exceeded for resources: ['consistencygroups']

My feeling is that this error message should be returned to the user with a 400 error code.

    Cinder consistency group returning generic error message

    When trying to create a consistency group with the quota reached
    already, the error raised to the user is the generic "ERROR: The
    server has either erred or is incapable of performing the requested
    operation. (HTTP 500)" message.
    This patch will make the error message return to the user with
    a 413 error code. Such as "ERROR: GroupLimitExceeded: Maximum number
    of groups allowed (10) exceeded'.(HTTP 413)"
