Closes #3633. Relaxing a metal with ISMEAR = 0 is fine, as noted in the VASP manual, provided SIGMA is sufficiently small (< 0.05 is the recommendation in the VASP manual).

If you have no a priori knowledge of your system, for instance, if you do not know whether your system is an insulator, semiconductor or metal then always use Gaussian smearing ISMEAR=0 in combination with a small SIGMA=0.03-0.05.

…MEAR = 0 and small SIGMA

Closes #3633. Relaxing a metal with ISMEAR = 0 is fine, as noted in the VASP manual, provided SIGMA is sufficiently small (< 0.05 is the recommendation in the VASP manual).

BadInputSetWarning should not be raised for ISMEAR = 0 relaxations with metals if SIGMA is small
