Add a new secret type known as "key" - it will handle adding the secret
objects that need a key (or passphrase) without a specific username.

+ This secret is a general purpose secret to be used by various libvirt
+ objects to provide a single key (or passphrase) as required by the
+ object in order to perform its authentication.
+ <span class="since">Since 1.3.6</span>. The following is an
example
+ of a key-secret.xml file:
+ </p>
+
+ <pre>
+ # cat key-secret.xml
+ <secret ephemeral='no' private='yes'>
+ <description>sample key secret</description>
+ <usage type='key'>
+ <key>key_example</key>

+
+ <p>
+ A secret may also be defined via the
+ <a href="html/libvirt-libvirt-secret.html#virSecretDefineXML">
+ <code>virSecretDefineXML</code></a> API.
+
+ Once the secret is defined, a secret value will need to be set. This
+ value would be the same used to create and use the volume.
+ The following is a simple example of using
+ <code>virsh secret-set-value</code> to set the secret value. The
+ <a href="html/libvirt-libvirt-secret.html#virSecretSetValue">
+ <code>virSecretSetValue</code></a> API may also be used to set
+ a more secure secret without using printable/readable characters.
+ </p>
+
+ <pre>
+ # MYSECRET=`printf %s "letmein" | base64`
+ # virsh secret-set-value 718c71bd-67b5-4a2b-87ec-a24e8ca200dc $MYSECRET
