Add a new secret usage type known as "tls" - it will handle adding the
secret objects for various TLS objects that need to provide some sort
of passphrase in order to access the credentials.
The format is:
<secret ...>
<uuid>...</uuid>
...
<usage type='tls'>
<name>mumblyfratz</name>
</usage>
</secret>

+ This secret may be used in order to provide the passphrase for the
+ private key used to provide TLS credentials.
+ The <code><usage type='tls'></code> element must contain a
+ single <code>name</code> element that specifies a usage name
+ for the secret.
+ <span class="since">Since 2.2.0</span>.
+ The following is an example of the expected XML and processing to
+ define the secret:
+ </p>
+
+ <pre>
+ # cat tls-secret.xml
+ <secret ephemeral='no' private='yes'>
+ <description>sample tls secret</description>
+ <usage type='tls'>
+ <name>TLS_example</name>
+ </usage>

+ <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. The
+ secret would be the passphrase used to access the TLS credentials.
+ 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.
