* Fixture for liblxc
Add a fixture to allow testing the lxc connection plugin both with and
without liblxc being present.
Also change the test from unittest to pytest.
* Update liblxc error message
The error is not specific to python2, so remove the version. Also add
a test for it.
* Migrate to options
Because the lxc plugin was only using PlayContext properties, using host
vars like `ansible_lxc_host` didn't work. This is fixed by instead using
the `get_option` method inherited from `AnsiblePlugin`.
The options are not yet available in the `__init__` function, so the
determination of the container name is moved to the `_connect` method,
which is the first time it is actually needed.
The default for the `remote_addr` option is removed, because the string
`inventory_hostname` is not very useful. At all. This seams to have been
spread with copy&paste and a bit of cargo culting. The variable priority
already takes care of setting the value.
* Add changelog fragment
* Fix for Py2.7
`TypeError: super() takes at least 1 argument (0 given)`
* Add plugin type to changelog fragment.
* Restore untemplated default
This partially reverts commit 429d8c8cfb.
