dev: add: aws-actions for ci / configs validation / eslint and prettier / global refactoring

[marcello33]

Description

This PR is meant for the following things:

• Configure the ci to use aws-actions to setup the credentials to deploy EC2 instances using open id connect. The ci will create a dedicated nodes network, execute the remote setup using express-cli and perform smoke tests to ensure everything works at every push or PR created. The continue-on-error will be removed once DevOps enable matic-cli repo to use oidc provider (thus enabling the ci to remotely deploy on users behalf).
• Add eslint and prettier into the ci and fail on warnings and errors.
• Introduce fail-fast approach via user configuration validation, so that whenever the --start command is triggered, express-cli will run a sort of dry-run to ensure remote matic-cli won't fail at a later stage.
• Refactor and cleanup the whole code (fix warning and errors due to prettier and eslint, remove unused code, unify ganache-start scripts, remove pleonastic templates...)
• Add additional documentation related to aws sso process for tokens expiration.
