Bug 1989584 - split out nimbus examples to new crate (#6980)

- Moved `components/nimbus/examples/` => `examples/nimbus/` so that it
  lives with the other examples.
- Set the Rust edition in the nimbus `Cargo.toml`.

 In this directory we have a command line interface that helps us interact with the Nimbus SDK.

 ## How to use
 In order to use the CLI, you would run it as an example:
 ```bash
-cargo run --example experiment -- -c ./examples/config/config.json show-experiments
+cargo run -p examples-nimbus-experiment -- -c ./config/config.json show-experiments

-```bash
-cargo run --example experiment -- -h
-```
