* A basic start on an lxd dynamic inventory script
The script is a fairly basic start on an lxd dynamic inventory script. Only tested on ubuntu 16.04 and currently only reports ipv4 container addresses. Improvements to come.
* Updated formatting, indenting and python3 support
Updated to work on python3
* Additional options read from the ini file
Added options for connection and group to the ini file and modified to use these.
Host returned is now the name by default. For non-lxd connection, the ansible_host var is populated with the ip address.
* Additional options for group and connection
* Minor change to re-run tests
