Hide bos extend currSiz debug message

[Martin-Zeithaml]

Proposed changes

This PR addresses Issue:

• Debug message bos extend currSize part of the zwe command output #490
• zwe internal config get not working in v3 zowe-install-packaging#4005

When the config file is above 4KB, it is processed by chunks. There is a debug message showing this information and is routed to stdout, which makes scripting challenging. See testing.
