Replaced all console.log with console.info, limit supported
console methods.
`console.info`, `warn`, `error`, `assert` are more meaningful
than generic `log`. This will also help prevent having log prints
left by accident.
Updated rule:
`"no-console": ["error",
{ allow: ["warn", "error", "info", "assert", "group", "groupEnd"] }
]`
