Use Case

As a developer
I want the tests to not include the offensive "ismaster" term
So that I don't become offended or distracted while working with the Node driver code

Unknowns

1. Should I create a global constant or create the constant in each test file?

Acceptance Criteria

• All instances of ismaster in the test files are replaced with a constant named LEGACY_HELLO_COMMAND

Implementation Requirements

• Create const LEGACY_HELLO_COMMAND="isMaster". Replace instances of isMaster with references to that constant. For example,
  `if (doc.ismaster || doc.hello)`becomes 
  `if (doc[LEGACY_HELLO_COMMAND] || doc.hello) {`
