Updated JSON Report Output for Validation Scripts

Proposal

The Validation Scripts have historically produced a number of reports geared toward human consumption, but no report has existed that provided a full accounting of results in a machine readable format.  A file named failures was produced in the output directory, but it contained only a subset of information about the execution run.  The following proposal is to create a new file ( report.json ) that contains a full account of all available information.  It would be produced on every run of the validation scripts, and would be suitable for consumption for tools such as VNFSDK or Dovetail as part of the certification program.

File Specification

The top level will include a summary of available execution metadata.

NOTE:  The tests and requirements entries are elided in the example below.
