Highlights

New CLI command syntax, run adles --help for details or checkout the Usage section in the README
Consolidated the vSphere helper scripts (e.g. vm-power) into a single command, vsphere . For usage, run vsphere --help.
ADLES now requires Python 3.6+. It is included or easily installable on any modern Linux distribution, Windows, and OSX.

Added

The CLI can now be invoked a Python module (e.g. python -m adles, python -m adles.vsphere)
Added two new specification fields to all spec types: spec-type and spec-version
New argument: --syslog. Configures saving of log output to the specified Syslog server.
Added progress bars to the cloning, power, and snapshot vSphere helper commands
Support the NO_COLOR environment variable (per no-color.org)
New dependencies: tqdm and humanfriendly
Debian package (See the GitHub releases page)

Failing to import an optional dependency will now log an error instead
of raising an exception and terminating execution.
Logs will not longer emit to a syslog server by default.
Syslog server will now only be used if the parameter is set.
Behind the scenes changes to commandline argument parsing that will
make adding future functionality easier and enable usage of other
third-party libraries that use argparse.
Lots of code cleanup and formatting
Bumped dependency versions
