[Feature Request] Add a resolve flag to when using --cfg to output the config

[davidcian]

🚀 Feature Request

Add some way to print the resolved configuration (for interpolations) when using the --cfg flag in the CLI.

Motivation

Is your feature request related to a problem? Please describe.

OmegaConf evaluates interpolated values lazily, which is a bummer when using the --cfg flag to output the config for debug purposes, since the values just print un-interpolated.

Pitch

Describe the solution you'd like
An extra flag, maybe --resolve in the CLI to print the resolved configuration.

Describe alternatives you've considered

An alternative is to just use print(OmegaConf.to_yaml(cfg, resolve=True)) in the code, but it would be better to not clutter the code with such a statement.

Are you willing to open a pull request? (See CONTRIBUTING)

Yes, but I'd need a pointer for where to look in the code.

thanks @Jasha10, I tried to assign the issue to you on GitHub but it won't let me 🤔 , then I ended up clicking the wrong button and accidentally assigned it to myself 😂
