Takashi Kajinami 03055de176 Detect maximum number of SEV guests automatically ...

Libvirt has implemented the capability to expose maximum number of
SEV guests and SEV-ES guests in 8.0.0[1][2]. This allows nova to detect
maximum number of memory encrypted guests using that feature.
The detection is not used if the [libvirt] num_memory_encrypted_guests
option is set to preserve the current behavior.

Note that current nova supports only SEV and does not support SEV-ES,
so this implementation only uses the maximum number of SEV guests.
The maximum number of SEV-ES guests will be used in case we implement
support for SEV-ES.
