Fixups to add enough default attributes to some roles to test them on an admin node. [2/7]

Aside from Chef 11 fixups, the default attributes are inteded to be a
placeholder until the chef jig is working well enough to handle
attribute import and export.

Roles that have been validated so far are:
 * deployer-client
 * dns-client
 * ntp-server
 * logging-server

Roles that have been half-validated (recipes run without error, but
functionality is missing:
 * bmc-nat-router: Needs the network BC to have injected attributed
   for the networks onto the node.
 * dns-server: Ditto

Roles that have nbeen modified, but not tested:
 * logging-client:  Cannot test until we have another node, as
   logging-client and logging-server cannot coexist on the same node.
 * ipmi-discover and ipmi-configure: Need real hardware to
   meaningfully test these barclamps.
 * provisioner-base and provisioner-server:  Need a semi-functional
   DNS server and network BC to make any reasonable progress here.
