feat: Add config file support for storage provider

[aidan46]

Supporting TOML and/or YAML files to pass config into the storage provider would make it easier to have a consistent configuration. Currently, the P2P config has been implemented to add support for TOML files. The other config values should have support for reading from config file too.

There's more to this than just "adding a config file".

• Do the CLI options override the respective config?
• Maintaining both CLI options and config file is a bit of a PITA, should we remove the CLI options all together?
• Should we support the "@" dialect?
• Do we need to provide an "init" command to generate a default config?
