Use Case

As a... driver developer
I want... to remove unused code paths
So that... I can reduce the complexity of the API surface we support

As a... node driver user
I want... to not have options in the public API that aren't intended for public use
So that... I can easily tell what options I should be relying on

User Experience

• `dbName` and `authdb`, two parameters in the public CommandOperation API but meant only for internal use, are removed

Dependencies

• authdb and dbName are used by removeUser, which should be removed before this work

Risks/Unknowns

• Confirm the non-use of authdb and dbName (beyond the known removeUser path)

Acceptance Criteria

Implementation Requirements

• none

Testing Requirements

• remove tests

Documentation Requirements

• authdb and dbName should be removed from the public docs as available parameters in CommandOperation

Follow Up Requirements

• release this change with the next major version
