[GOBBLIN-1780] Refactor/rename YarnServiceIT to YarnServiceTest

[AndyJiang99]

Dear Gobblin maintainers,

Please accept this PR. I understand that it will not be reviewed until I have checked off all the steps below!

This renaming is done as YarnServiceTest currently is disabled on CI testing. We would like to add unit tests in this file that are run during CI, but this requires removing some components. This rename is so we don't override YarnServiceTest Git history, simply a rename to YarnServiceIT. After renaming the tests to YarnServiceIT, there will be another PR that has a new file of the original name (YarnServiceTest.java) will be created, new unit tests will be created there, and those new tests will run in CI testing.

  3. Subject does not end with a period
  4. Subject uses the imperative mood ("add", not "adding")
  5. Body wraps at 72 characters
