[TASK] Support dockerized gadgets in blueprint manager

[drewstone]

Overview

We want the ability to have a template that any developer can use to deploy dockerized gadget. This can take 2 shapes:

1. The gadget functionality is inside a docker image.
2. The blueprint manager deploys a dockerized gadget.
3. Add a new target for Docker.

How do you define your environment?

How do we want blueprint developers to define the environment they run in?

The blueprint template provides us with a Dockerfile, will we:

• be pulling and building it ourselves?
• pulling from a registry?

If the latter, where will the developer specify the information? (registry, image name, etc)?

We support defining this in blueprint.json, but currently do nothing with it: https://github.com/tangle-network/gadget/blob/9ea1aa039fac85573997fc975e155a60205939c5/macros/blueprint-proc-macro-core/src/lib.rs#L459-L466

Depends on tangle-network/blueprint-template#10

@drewstone I'm not sure what this means, can you expand on it?

Create the CLI task, but initially sounds like adding the right config to the Cargo.toml as part of the blueprint template.
