Enables an LXC server's configuration as an inventory source for LXC
containers.
In LXC, containers can be defined with an "lxc.group" configuration
option that is normally used with lxc-autostart -g. Here, we are using
the same option to build Ansible inventory groups.
In addition to being grouped according to their lxc.group entry (or
entries, as LXC allows a single container to be in multiple groups),
we also add all containers (including those with no lxc.group entry)
to the "all" group.
Has already been transferred as a tempfile.
This fixes the error in https://github.com/ansible/ansible/issues/16125
but there may be higher level issues that should be fixed as well (other
modules might be able to cause status fields like failed and changed to
return a censored string instead of a bool). So leaving 16125 open for
now.
If someone run:
ansible all -m file state=present
The error message is "Missing target hosts" which is misleading, since
the target hosts is here, the problem is the missing '-a'.
* In the VariableManager, we were not properly tracking if a file
had already been loaded, so we continuously append data to the end
of the list there for host and group vars, meaning large sets of data
are duplicated multiple times
* In the inventory, we were merging the host/group vars with the vars
local to the host needlessly, as the VariableManager already handles that.
This leads to needless duplication of the data and makes combining the
vars in VariableManager take even longer.
