Use inspec reporting framework instead of cookbook reporter

[chris-rock]

InSpec ships with an automate reporter now and we should harmonize. This works without any issues with Automate 1.x and 2.x if a direct connection exists.

Special case is the reporting via Chef Server:

• signing mechanism is required for Chef Server
• we may need to extend InSpec to add a hook to inject a function from this cookbook to be executed for every report and added to the header
• the report continues to go via the Chef Server

Not sure if this is a priority atm. Assigning to keka to weigh in.
