feature: custom faucet addition

[Anmol1696]

Overview

Alot of the chains are not able to support cosmjs facuet, which causes the issues around scaling.

Proposal

Create a custom go facuet binary that runs inside the docker image of the chain. This faucet will be a wrapper around running exec commands for tx send tokens.

We will also have the type of faucet be:

chains:
- name: osmosis-1
  type: osmosis
  numValidators: 1
  faucet:
    type: starship-faucet
    resources:
      ...

starship-faucet will have the same endpoints as cosmjs faucet, which are:

• /status
• /credit

Implementation

• Go microservice with /credit endpoint
• Need a queue, with the requests or a lock on performing the send transfer
• Alternatively: Use concurrent addresses, more similar to cosmjs-faucet

Test

• Add tests for current and new faucets
• Test against non cosmjs compatible chains: injective, evmos

[Anmol1696]

Need to create a job queue from /credit endpoint. The job itself should transfer tokens based on exec.Command using the chain binary to perform a send-transfer token request.
