Fix lxc plugin options (#7369) * 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 commit429d8c8cfb. --------- Co-authored-by: Felix Fontein <felix@fontein.de> (cherry picked from commit1bf5a44a77) Co-authored-by: Corubba <97832352+corubba@users.noreply.github.com>
