lib/config: add environment variable to set config file

Previously it was assumed that `config.json` would be placed in
the same directory as the rest of CodiMD without any optional override.

This allows to override the path to the `config.json` by setting
`CMD_CONFIG_FILE` to the canonical path of the desired config file.
