Add a file adapter to connect to JSON files directly

Until our File-based adapter can connect to JSON natively there is a fairly simply workaround users can implement in the meantime:

You can use the Jetty HTTP server instance that comes with DV as the lightweight web server to host your JSON files. It's recommended that you create a symlink to an external folder and place the symlink in this directory:

<TDV Install>apps/server/webapps/home

Then you can access the files using a REST data source adapter (Instead of the File-based adapter) with the URL:

http://localhost:9400/<name of your symlink folder>/

And then create individual GET operations in the REST adapter for each file you need to access.

Use case from Brian Anderson:

We get numerous data files that are constructed with JSON. We need to import these files, transform them then either output them as database views, or export them as csv files.
