1058380: Subscripton Manager plugin reporting Subscription Management when RHN is in use
Add test cases for logutil
Move mocking of is_valid_server_info to fixture

test_managercli was mock.patch'ing is_valid_server_info
at module scope for use for it's tests, but other test
modules call mock.patch.stopall() which would stop it
as well. So is_valid_server_info would sometimes be not
mocked, depending on test order. Some tests always fail
if it's not mocked. So move it into SubManFixture.setUp
Make logutil tests assert something.

mock.patch.dict os.environ for the the debug tests, so
the os.environ doesn't pollute other tests.
1086377: Next system check-in not displaying in RHEL 5.11

Call used to determine if rhsmcertd is on worked for RHEL 6 and 7,
but not RHEL 5. Subprocess in Python 2.4 did not have the check_output
method. Subprocess.call gives a consistent answer in all versions. 0 if pidof
has a process number returned and 1 if it does not.

Add ContentActionClient

Replace RepoActionInvoker in main ActionClient with a
ContentActionClient.

Split BaseActionClient to its own module.
Add ostree_action_invoker (ostree repo action)

Hook it up into ContentActionClient
Add ContentActionPluginConduit plugin.

This conduit is for plugins that will add
content actions used in ContentActionClient.

Rev plugin api version to '1.1' since this is
a backwards compatible change. And I remembered.
Add a dummy yum_content plugin for testing
Load content actions from plugin class search

The content action client, now uses the subscription
manager plugin hook 'content_plugin_search' to find
ContentActionInvoker style classes, construct them,
and add them to the list that ContentActionClient
will run.
Replace odd usage of 'repolib' name.

This code actually passes a RepoActionInvoker now,
so remove the confusing repolib name.
entcertlib.repo_hook can be content type agnostic

More than likely, we can remove this tightly coupled
if we make sure entcert updates are via an ActionClient
that will follow up and update content.
Add test for ContentActionPluginConduit
