feat(dell-config): add Dell server utility scripts

Add Dell-specific server management scripts:

- fixeth.sh: Ethernet interface naming fix script for Dell
  servers that require consistent network interface naming
  after BIOS/firmware updates or hardware changes

- omsa.sh: Dell OpenManage Server Administrator installation
  script for hardware monitoring, health status, and
  out-of-band management capabilities

These scripts support Dell PowerEdge server operations in
the KNEL infrastructure, enabling hardware monitoring and
consistent network configuration.
