Refactor of cli, recipe and query

[worldomonation]

The previous PR became rather polluted due to my mistakes, plus it had rebase/merge issues.

I've remade the PR with a new branch, with rebasing done (hopefully) properly this time.

Changelogs still apply from the previous PR, and have been copy/pasted here:

• setup: removed script entry point for adr-query.
• adr.cli: removed cli() as the entry point for recipe.
• 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.
• 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.
