Support full log contract from plain js Console in metalog.Console

[georgolden]

Problem

Console interface not fully implements js Console interface.

debug, error, log, info, warn contracts are different from js Console contracts.

It must handle 2 scenarios: multiple objects to log, or string as a first argument and objects to replace substitution parameters as rest.

Solution

For those methods - implement handling different arguments based from first argument type. It can be an object - rest are objects or a string - rest are objects to replace substitution parameters.
