zcli: Zitadel Command line Interface

[muhlemmer]

As a user I want to be able to send commands to Zitadel from the CLI.

The cli will be a separate binary and most probably a separate repository.

Acceptance criteria

• Non-interactive command line program to send JSON formatted requests
• Interactive CLI, where message fields are asked from the user, based on the proto fields. These questions might be auto-generated based on proto reflect or a library.
• Integrate import migration (currently part of zitadel-tools)

started a private project beacuse i was curious about proto generations: https://github.com/adlerhurst/protoc-gen-go-cli/tree/init

the branch mentioned adds a new subcommand to the standard binary. A user will be able to call zitadel alpha client user add for example
