sap_vm_provision: Add SLES 16 images, fix sshd_config and add python311 workaround

[marcelmamula]

Changes

• Add SLES 16 images that were recently published in Clouds providers
• Add conditional for SLES 16 to load correct /usr/etc/ssh/sshd_config instead of /etc/ssh/sshd_config
• Add fix for missing python311 for SLES 15 GCP images sap_vm_provision: gcp_ce_vm provisioning no longer connects via SSH #117

Tests

This change was tested on AWS, GCP and AZ for SLES_SAP 15 SP7 and SLES_SAP 16.0 images.

Added extra sanitization for slower VMs, where even raw module attempt would fail with Unreachable.

Example for SLES_15 SP7 PAYG, which does not have Python 3.11
