[EPIC] Create a basic Omni validator to consense one XBlock

[Zahoor Mohamed]

Summary

Create base structure for Omni validator so that one XBlock message is consensed.

Motivation

We should be able to send a XBlock to the validators and make them attest and consense on it.
This will give as base for us to add more validator related stuff later.

Implementation

• Create a embeded cometBFT App which can take a XBloxk and consense
• Create mock XBlock injector
• Create a mock relayer which prints a consensed XBlock
