[ssh] Bug Fix: Change how ssh vm reads the ssh client logs

[Vivian Thiebaut (vthiebaut10)]

Fix: #4915 (comment)

• ssh vm reads the logs from ssh client and ssh proxy to delete sensitive information when it is no longer needed and print helpful error messages for known errors. Our approach to do that was causing ssh banners to be printed after the ssh process was terminated, and not before authentication.
• Known issue: we are no longer able to read ssh proxy error channel when the user is running the command from a linux machine to connect to a local user on an arc machine. That is not a breaking change, but users in this particular situation will not get a helpful error message if there is an error with the proxy.

If you want to release a new extension version, please also upgrade the version defined in setup.py

[Vivian Thiebaut (vthiebaut10)]

Xing Zhou (@zhoxing-ms) I was planning on upgrading the version only after all the open PRs for the next release are merged and I have the chance to run some final tests. For now I'll just remove the changes in the HISTORY.md file for this PR.

[Xing Zhou (zhoxing-ms)]

Vivian Thiebaut (@vthiebaut10) OK. Or I can merge this PR first, and you can add new content to the history notes of subsequent PRs.

[Xing Zhou (zhoxing-ms)]

In the future, if you do not want to release a new version immediately, I suggest you add comments in PR to tell us
