Label implementation

[calekennedy]

#3
Implementation of features addressing this issue:

Client.listApplicantsLabels(applicant_id);
// already implemented
// added documentation to readme
// added tests

Client.updateApplicantsLabels(applicant_id, label_title, is_completed);
// added implementation
// added documentation to readme
// added tests

Client.listStagesLabels(stage_id);
// added implementation
// added documentation to readme
// needs test coverage

That covers all of the label management functionality listed on the v2 api documentation

Test runner seemed to fail in the CI process. Let me know if I can help solve the issue. Tests are passing locally.

Thank you for the PR @calekennedy . I will review this shortly and run tests before including your edits

[calekennedy]

Is there anything I can do to help with this PR?

[calekennedy]

I think the problem with this PR is the OIQ api versioning. Is there any chance we can pull this in?

[stephnr]

I can review this. Perhaps we can change the way the tool itself perform tests. I have a new tool in use; wallaby. Let me get this working with mocha/chai/nock to organize the tests better

@calekennedy make sure to grab the latest code with the improved testing suite and retest your code
