Most of the augeas test files use ::CONFIG:: to pull in the master
config file for testing. This ensures that entries added to the config
file are actually tested by augeas.
This identified the missing admin_max_clients example in the virtlogd
config file, which in turn prompted a change in description of the
max_clients parameter, since these daemons don't have separate
readonly & readwrite sockets.

The global log buffer feature was deleted in:
commit c0c8c1d7bb
Author: Daniel P. Berrange <berrange@redhat.com>
Date: Mon Mar 3 14:54:33 2014 +0000
Remove global log buffer feature entirely
A earlier commit changed the global log buffer so that it only
records messages that are explicitly requested via the log
filters setting. This removes the performance burden, and
improves the signal/noise ratio for messages in the global
buffer. At the same time though, it is somewhat pointless, since
all the recorded log messages are already going to be sent to an
explicit log output like syslog, stderr or the journal. The
global log buffer is thus just duplicating this data on stderr
upon crash.
The log_buffer_size config parameter is left in the augeas
lens to prevent breakage for users on upgrade. It is however
completely ignored hereafter.

So far the virt-aa-helper tests only checked the return code and thereby
catched aborts like issues failing to parse the XML. But there is one
category of virt-aa-helper issues so far untested - not generating the
expected rule.
This adds a basic grep based checks after each test to match against the
rule that is expected to be added by the test.

nvdimm memory is backed by a path on the host. This currently works only via
hotplug where the AppArmor label is created via the domain label callbacks.
This adds the virt-aa-helper support for nvdimm memory devices to generate
rules for the needed paths from the initial guest definition as well.
Example in domain xml:
<memory model='nvdimm'>
<source>
<path>/tmp/nvdimm-base</path>
</source>
<target>
<size unit='KiB'>524288</size>

Reviewed-by: John Ferlan <jferlan@redhat.com>
Long ago in commit dfa1e1dd53 the scheduler weight was accidentally
hardcoded to 1000. Weight is a setting with no unit since it is
relative to the weight of other domains. If no weight is specified,
libxl defaults to 256.
Instead of hardcoding the weight to 1000, honor any <shares> specified
in <cputune>. libvirt's notion of shares is synonomous to libxl's
scheduler weight setting. If shares is unspecified, defer default
weight setting to libxl.
Removing the hardcoded weight required some test fixup. While at it,
add an explicit test for <shares> conversion to scheduler weight.
