Enable Scopelint Linter (#2049)
* added scopelint and correcte issues found

* corrected scopelint issue

* made updates based on Ivan's suggestions

Most were around naming conventions
Some were false positives, but I kept them since the test.Run could eventually be changed to run in parallel, which could cause a bug
Others were false positives.  Added // nolint: scopelint
