[BE] New feature to remove or disable the Examples tab, and scrub PII from the content of the Explain tab. (MongoDB)

Suggested implementation:

1. BE will parse fingerprint and send list of placeholders to FE.
2. FE create exact numbers of inputs based on placeholders.
3. 2. FE will create request on BE to get explain result, but instead sending whole query as param it will send only queryid and placeholders arguments from inputs.
4. FE getting result as response on previous request.
