Discovery service debug mode breaks the ZAAS

Describe the bug

Discovery service debug mode somehow breaks the startup of ZAAS component so Zowe never starts completely
Seems to be introduced in Zowe 3.1, reproduced on 3.1, 3.2, not reproduced on 3.0.

Steps to Reproduce

1. Set components.discovery.debug: true
2. Start Zowe

Reproduce the failure by setting components.discovery.debug to true and starting Zowe, comparing behavior with Zowe 3.0 and later versions. Use the reported Discovery TLS and Spring/Tomcat stack trace to locate the debug-mode interaction with ZAAS startup. Done means Zowe starts completely without repeated TLS debug errors.
