fix: Fix of Tomcat customizers to be supported also by reactive stuff

[pj892031]

Description

The original issue was when a customer configure zowe.yml to use keyring and provide the keyring URL with just douple slashes (not four). All services except the caching service fix the issue in Tomcat. The handler responsible to fixing URLs was not applied for the caching service, because the implementation is only for servlet implementation. Caching service and API catalog uses WebFlux. Therefor the handler was ignored and not applied. The workarround was to use 4 slashes. More information about the error itself is in the linked issue.
