S3 credentials leak in log files

S3 credentials used to create a Secondary Storage instance are leaked to the following files:

- /var/log/cloudstack/management/access.log
- /var/log/cloudstack/management/management-server.log

Although the debug mode is enabled, I don't recommend logging secrets like S3 credentials.

Example entry containing the S3 credentials (sensitive information is redacted):

```

### versions

CloudStack: 4.20.0.0
Hypervisor: KVM
Secondary Storage: Ceph RGW S3
Distro: Ubuntu 22.04 LTS

### The steps to reproduce the bug

1. Deploy CloudStack Management server version 4.20.0.0
2. Create a Secondary Storage using S3 credentials (accessKey and secretKey)
3. Grep the log file directory for the secret key: `grep -R /var/log/cloudstack/management/{access,management-server}.log`

### What to do about it?

Redact at least the secretKey from the log entry.
