feat(objectDoesMatch): provide mongo-style comparison search operators

[sumartoyo]

Stein can search only with equals search param, such as

search = {
  "registered_date": "2019-10-01"
}

This PR provides a functionality to search using MongoDB-style Comparison Query Operators such as

search = {
  "registered_date": {
    "$gte": "2019-10-01",
    "$lt": "2019-11-01",
  },
}

This way we can have more expressive search functionality.

Edit: now also supports Logical Query Operators such as

search = {
  "$or": [
    {"role":"admin"},
    {"department":"finance"}
  ],
}

Have you tested this one?
I don't see any conflicting logic in comparison

I have tested all of the operators/combinations manually by requesting to the server. Could be better if we have unit test for this.
