* Metadata.json can be generated with the rake tasks.
* Use 'metadata[cookbook]' and 'metadata_all' to generate .json.
* Application readme needed a few more clarification points.

The rakefile shouldn't delete the metadata task, since the
ability to generate JSON metadata from the cookbooks directory
is still useful.

Lets also ship the metadata in JSON in the cookbooks, so others can
make use of it without having to run any Ruby.

The 'first' method caused typeerror and no method was a nilclass error,
so the search for fqdn uses map block, per the recipes search on the wiki.

Added protocol selection support, UDP vs TCP.

Handle rsyslog.d files - delete client remote.conf on the server and
server.conf on the client.

Updated README.
