This change makes it easier to follow retrieval of parent directories.
Additional os.path operations replaced with their pathlib.Path equivalents
to keep module usage consistent.
The goal was to support passing a list to install, enable, etc. in order
to improve performance. Passing lists to most of the functions was less
practical than iterating through the items from the top level.
`reckless help <cmd>` previously called the function docstring. This could
be updated to use the subparser help, but would require a strict naming
convention or a dictionary. Providing a hint to use the built-in
contextual help via the option flag is hopefully sufficient.
Regtest environments commonly use explicit definition of the config
file for lightningd. This can be queried and utilized by default,
saving redundant definitions between lightning and reckless.
A simple standalone python executable to track plugin repositories, clone
to /tmp, install requirements, test plugin runs, then install and enable in
lightningd and in the config.
Changelog-Added: Reckless - a Core Lightning plugin manager
