[PATCH v3 6/7] virsh: add --disable-deprecated-features flag to domcapabilities

[Collin Walling <walling@xxxxxxxxxxxxx>]

Add a new flag, --disable-deprecated-features, to the domcapabilities
command.  This will modify the output to show the 'host-model' CPU
with features flagged as deprecated paired with the 'disable' policy.

virsh domcapabilities --disable-deprecated-features
