feat: SLES15 enablement, HAE detection

[marcelmamula]

Enhancement: Adds additional steps for SLES15 enablement:

• High Availability Extension detection
• Package list updated to remove SLES4SAP specific package
• Cluster destroy adjusted to avoid failure when corosync-qdevice was not present
• Removed logd check, because it is part of cluster packages and it should not be checked before packages are installed on SLES15
• Added gather facts for NIC for corosync template.

Additionally main.yml was reordered to allow variable checks before package installation.

Readme was updated to note higher Service Pack requirement for both SLES and SLES4SAP, because of detected dependency on pattern patterns-ha-ha_sles, which failed to install using package module because of samba client version mismatch.

Reason: Adding coverage for SLES15 after cluster deployment verification.

Result: Testing completed on both SLES4SAP 15 SP5 and SLES15 SP5 with HA, cluster creation and destroy are working.
