rsyslog_client is producing broken config files

[Logan V]

rsyslog_client when running after lxc_hosts is producing a logging configuration that looks like this:
# Ansible managed

# Log files
$InputFileName s
$InputFileTag s:
$InputFileStateFile state-s
$InputFileFacility local7
$InputFilePollInterval 1
$InputFilePersistStateInterval 1
$InputRunFileMonitor

$InputFileName e
$InputFileTag e:
$InputFileStateFile state-e
$InputFileFacility local7
$InputFilePollInterval 1
$InputFilePersistStateInterval 1
$InputRunFileMonitor

$InputFileName t
$InputFileTag t:
$InputFileStateFile state-t
$InputFileFacility local7
$InputFilePollInterval 1
$InputFilePersistStateInterval 1
$InputRunFileMonitor

$InputFileName (
$InputFileTag (:
$InputFileStateFile state-(
$InputFileFacility local7
$InputFilePollInterval 1
$InputFilePersistStateInterval 1
$InputRunFileMonitor

$InputFileName )
$InputFileTag ):
$InputFileStateFile state-)
$InputFileFacility local7
$InputFilePollInterval 1
$InputFilePersistStateInterval 1
$InputRunFileMonitor

Causing this rsyslog startup failure here: http://logs.openstack.org/49/501249/6/check/gate-openstack-ansible-openstack-ansible-ceph-ubuntu-xenial/83d4f27/logs/ara/result/2722d656-9221-48a5-808a-8794783c5c60/

The reason why this is happening is because the log file list is currently cast as a string containing "set()" there, due to not being cast as a list.

    Cast the log file list as a list

    The log file list, when empty, is cast as a string containing "set()",
    which produces a broken log config file.
