devenv inputs develop <input> [dest]

[domenkozar]

I find it often I'm developing on one of the inputs so I'd like a command that will override that input and copy it into a folder locally.

We should override the input using devenv.local.yaml.

Subcommand should be idempotent, if dest already exists and points to the input, then proceed just overriding the input.

Depends on #1030
