Generate custom token pool via CLI in QA/Staging network

Description: This story is to propagate [#14](https://github.com/liftedinit/roadmap/issues/14) to the QA/Staging network so that Liftoff Program members can interact with it.

Story ROI
Customer Need: Liftoff Program members will now be able to interact with the feature. A Liftoff Program team has requested a way to generate a custom token on an existing network to replace their in-app currency with a blockchain-based token.

Business Objective: Enabling more development and use cases to occur on the Manifest Network. This can lead to more network usage.

**As a developer, I want to generate custom tokens so that end-users can transact them.**

- [ ] Should function as required in [#14](https://github.com/liftedinit/roadmap/issues/14).
- [ ] Should be able to be demoed in the QA/Staging network.

--------------------------
Tasks

- [ ] Propagate to the QA/Staging environment for testing (RC)
- [ ] Fix bugs
- [ ] Demo the story to the team (QA/Staging network) (Feature branch).

Start by reading roadmap issue #14 and the linked PRD to determine the required custom-token behavior. Then identify the QA/Staging deployment and feature branch involved; done means the feature works as required, is available for testing on QA/Staging, and can be demonstrated to the team.
