[libvirt] [PATCH v7 10/11] util: Add virstoragetest to parse/format a tls='yes'

[John Ferlan]

From: Ashish Mittal <Ashish.Mittal at veritas.com>

Add a test case to verify TLS arguments are parsed correctly for
a VxHS disk. This includes saving off a found tls-creds into the
storage source @tlsAlias field since that's what's used to link
the TLS object for the authentication credentials and the disk.

Test case verifies that XML is generated correctly for a VxHS disk
having TLS enabled.
