Description
What's the issue?
There is a couple of places where 'cbbackupmgr' may implicitly scrape sensitive information where it shouldn't. For example:
1) 'cbbackupmgr' logs the S3 access keys at the beginning of running a sub-command (6.6.x+ only)
2) Some of the (platform specific) commands run when collecting system information may collect the command line arguments of other processes on the system.
Steps to reproduce #1
1) Install Couchbase server 6.6.0-7897 on a windows server 2016
2) Run backup to S3.
3) Run collect-logs in S3 using cbbackupmgr, logs collect ok but it display all S3 credentials in raw text.

We need to hide it as in password
This issue prevent upload logs to MB-40764
Verification for 6.5.2-6624 on Windows:
This ticket seems to discuss two related issues.
1. The first issue is that cbbackupmgr logged AWS credentials, this only affects versions 6.6.x and above.
Cbbackupmgr in version 6.5.2 cannot backup to s3 so it is not affected by this issue.
2. The second issue is that process arguments were being logged revealing sensitive information.
We can check that this is fixed by running various cbbackupmgr sub-commands and checking if process arguments are leaked and if any sensitive information is revealed.
I created a backup archive, performed 3 backups and used the info command to check which backups exist.
I then used the collect-log sub command to produce the following logs:
cbbackupmgr-collectinfo-my_archive-2021-01-28T182737.zip
I performed a case-case-insensistive grep for 'administrator' and 'password'. In addition, I do not seem to see any process arguments.
(It's definitely worth if someone could take a second look at these).
An additional collection where I also performed the restore command.
cbbackupmgr-collectinfo-my_archive-2021-01-28T185045.zip
The grep results:
