-    Configures dnsmasq to add cnames for teuthology remotes. The task expects a
-    dictionary, where each key is a role. If all cnames for that role use the
-    same address as that role, the cnames can be given as a list. For example,
-    this entry configures dnsmasq on the remote associated with client.0, adding
-    two cnames for the ip address associated with client.0:
-
-        - dnsmasq:

-            - c0.example.com
-
-    If the addresses do not all match the given role, a dictionary can be given
-    to specify the ip address by its target role. For example:
-
-        - dnsmasq:
-            client.0:
-              client.0.example.com: client.0
