[Machinery] Machinery 1.5.0 is out!

[Federica Teodori]

Hi,

The Machinery team had again a successful sprint and is happy to announce the release of Machinery 1.5.0.

This release will bring you two new shiny options:

- machinery list --short 
By adding --short to your *list* command machinery will show you only the description names, so you can pass the
output to any other tool you like, or simply have a synthetic overview of all the machines you've inspected.

- machinery inspect --skip-files=arg HOSTNAME               
The --skip-files parameter gives you the possibility to omit specific unmanaged files or directories (large data
directory, anyone?) during the inspection.
Feel free to pass as argument either one file, a directory, or a comma separated list of names. 

While at it, we have improved the message reported in case your system descriptions are in need of an update and also
fixed an issue you might have experienced by inspecting a RHEL system with changes in the managed files.

This translates to the following changelog:

## Version 1.5.0 

* Fix issue with changes of managed files on RHEL
   ( https://github.com/SUSE/machinery/issues/636 )
* Add `--short` option to list command for showing a short list of all descriptions
* Improve error output for system descriptions which have outdated formats
* Add `--skip-files` option to `inspect` command for unmanaged files

In case you haven't installed machinery yet, go and grab it from http://machinery-project.org
We hope you'll enjoy this release and we're looking forward to receiving your feedback!

Sincerely, 

Your Machinery team
