The Node driver's Db.command() helper currently supports all options that the command helpers support.  This is problematic for two reasons:

• the runCommand helper is generic and should not support options that are specific to certain commands
• some options, such as `readConcern` are prohibited from being automatically applied by the driver in the generic "command" method (see https://github.com/mongodb/specifications/blob/master/source/read-write-concern/read-write-concern.rst#id22)

Our `db.command()` helper should only consider options that are not command related (e.g, bson serialization options).

Acceptance Criteria

• Remove the following options in v6

The following options are supported because of the inheritance design of our operations layer and should be removed:

  willRetryWrite?: any;
  omitReadPreference?: any;
  writeConcern?: any;
  explain?: any;
  readConcern?: any;
  collation?: any;
  maxTimeMS?: any;
  comment?: any;
  retryWrites?: any;
  dbName?: any;
  authdb?: any;
  noResponse?: any;
