Support to customize which images/containers to run

🆕🐥 First Timers Only

This issue is reserved for people who have never contributed to Hedera or any open source project in general.
We know that creating a pull request (PR) is a major barrier for new contributors.
The goal of this issue and all other issues labeled by 'Good First Issue' is to help you make your first contribution to Hedera.

👾 Description of the issue

When using the Local Node for testing purposes or scripting, there are many images/containers that might not be needed.

For example, when working only with the Relay, the Hedera Explorer might not be used. In addition, there are "complementary" containers that usually are not used in testing, e.g., grafana and prometheus.

As another example, a minimal setup with the Relay would have only these images: network-node (consensus-node), mirror-node-rest, json-rpc-relay and any other dependency to run these.

Proposed Solution:

Enable support to specify which images/containers to run. Ultimately, as I dev I would like to configure which containers to start.

Ideally, this configuration should be possible with both the CLI and a config file.

@acuarica can you add some more details how to start working on the issue. I would have no clue ;)

@hendrikebbers is there something that's not clear about the problem? I wouldn't have a clear idea on how to start on this unless I investigate the repo.
