[Feature] Faucet command to receive funds on development environments

[jrchatruc]

🚀 Feature

Add a faucet command to the CLI that gives users some funds on development environments.

Motivation

To test functionality on their apps on development environments (see this issue for a proposal on development nodes), users need to have funds available for the transactions they submit on their applications.

Implementation

This could be done by adding an endpoint to development nodes and then have the faucet call it. The endpoint would send a small amount of money from the development node's account to the caller.

This is a great idea, I will likely attempt to implement this for development environments
