[libvirt] [PATCH 1/2] virsh: flexibility in CA cert and user cert/key

[Doug Goldstein]

Allow the CA certificate to come from the user's home directory or from
the global location independently of the client certificate/key pair.

Mostly for the case when each user on a system has their own cert/key
pair but the system as a whole shares the same CA.
