Add nats command line utility

[tamis-laan]

It would be so nice to add the nats command line utility similar to synadia/nats-server:nightly.

This would really help when doing development.

We have a companion container https://github.com/nats-io/nats-box for all that

That is true and helpful, but when using docker compose for example one would need to create a seperate nats-box container for and keep it running. It's way more helpfull to use docker compose exec and run within the nats server container. The alternative would be to use docker run but this requires opening ports to connect.

It's also nice because connecting from within the server container one already has full authority and should be able to directly connect to the server without the need for credentials similar to postgresql. This makes management way more easier.

So having the nats cli within the server container would be of great help and benefit.

nats does not have this "full authority" concept, there's nothing special about the server container or others.

Well postgresql includes psql and you can authorize local connections without the need for authentication with:

# TYPE  DATABASE        USER            ADDRESS                 METHOD
# Allow local connections without a password
host    all             all             127.0.0.1/32            trust
host    all             all             ::1/128                 trust

Which is really handy
