Feature/enhanced file system

Fix collector provider installation detection for 19.216-33 on Systemd platforms

Added cutoffTimestamp and cutoffRelativeTime as optional properties.

This would fix #155.

As of 19.216-33, the collector uses Systemd on platforms that support it and no
longer drops off an `/etc/init.d/collector` file.

This should mean that the Systemd hack at
https://github.com/SumoLogic/sumologic-collector-chef-cookbook/blob/v1.2.23/providers/default.rb#L169
can be deleted whenever it's safe to re-break compatibility with earlier
versions of the collector.

These are automatically generated as of ChefSpec 7.1.0.

Offenses:

libraries/provider_source.rb:34:21: C: Reverse the order of the operands /password/i === config_json.
          sensitive(/password/i === config_json) # rubocop:disable Style/CaseEquality
                    ^^^^^^^^^^^^^^^^^^^^^^^^^^^

Prep for v1.2.23 release

relates to #141

We now allow using `node['sumologic']['init_style']` with any valid chef provider. Default is `nil` and will defer to ohai unless overridden.

Note: it does not attempt an validation that you chose a valid provider.
