Hi, [~tzulitai], [~eronwright],
I've added unittest to capture the securityconfiguration keytab related settings. Also, I've refactored the code to use the existing of krb5.keytab file instead of `_KEYTAB_PATH`. 

For the integration test code, I will create a different JIRA to follow, otherwise, it's better to a smaller PR rather than fixing everything in one PR.

Could you please take another look at the PR?

> The local keytab path in YarnTaskManagerRunner is incorrectly set to the ApplicationMaster's local keytab path. This causes jobs to fail because the TaskManager can't read the keytab.
