Allow configuring parseable instance with a toml file

[de-sh]

Currently, parseable configs are extracted from env variables, this could become simpler if configs can be extracted from a TOML file.

[de-sh]

We can use something like https://docs.rs/config/latest/config/trait.FileSource.html

so techincaly .toml is better for doing the config loading, some main pros

• multiple config, like config.prod.toml or config.staging.toml
• env is just string file, but toml can supports, boolen, arr etc
• Its can be conrtolled where to be loaded and where not to be

Yes Harsh, that is why the issue was raised. Would be really helpful for users to have an easy to configure setup where we need not have to keep passing env variables and wonder why they break sometimes, such as in the case of inaccessible environments like that in the case of systemd services.
