dashboard:make the image min_disk and min_ram valule empty,error report after user update image ,not before

[wangxiaoxian]

The Dashboard UI Bug :
dashboard->Project->Compute->Image->Edit mirror.Then make the Minimum Disk and Minimum RAM value null.we can also click the "Update Image".we will get the inf "Error:Unable to update the image".The UI should check the empty value and give the errors to inform the user of a problem.

The Compare:
If we give the "Minimum Disk" and "Minimum RAM" an invalid value,the UI will give user the hint about invalid value normally and the "Update Image" can't be clicked as usual.

In fact,in the Chinese interface,after clicking "update mirror",it shows "can't delete the mirror".

    Make fields in image edit required

    Make the min_disk and min_ram fields in the image edit form required,
    so that the form can't be submitted with empty values for those fields,
    which always results in an error.
