Made multiple changes, not all of them complete or as modularized as I like.

• setup: removed script entry point for adr-query.
• adr.cli: removed cli() as the entry point for recipe.
• adr.cli: copied some code from adr.query; ultimate goal is to encapsulate all query calls.
• adr.cli: created new method main() which is the new entry point for both adr query and adr recipe/
• adr.cli: switched to using subparsers to support the above.
• adr.cli: extracted common calls between recipe and query to helper functions.
• adr.query: changed log import from adr.cli to reference by name.

Carried on with additional refactoring on master branch in the forked repository:

• setup: removed adr-query entry point
• adr.cli: removed query handler that was temporarily copied to adr.cli:query_handler for changeset c53fe73
• adr.query: refactored how the query file is found and read. Now it assumes the name exists, due to previous checks being present.
• adr.query: run_query (old) renamed to load_and_run_query; code logic remains unchanged.
• adr.query: new function run_query created to mirror run_recipe. It wraps around the top level business logic of the old cli method.
• adr.query: marked older methods as deprecated.
• adr.query: added docstrings.

Please rebase this on the latest master, I added a whole bunch of new ARGUMENT_GROUPS and it looks like these might be lost.

Incorporated upstream changes, moved the new ARGUMENT_GROUPS from cli.py to recipe.py like in the refactor.
