[Staging] Add SLES support for AMD gpu-operator

[Priyankasaggu11929]

(based on comment #365 (review) from the original PR)

Motivation

This PR aim at adding support for SUSE Linux Enterprise Server (SLES) 15 SP5+ to the AMD GPU operator.

Technical Details

• 781c5b5 - add support for detecting SLES nodes and automatically selecting appropriate AMD GPU driver versions

  • add new slesCMNameMapper to parse SLES version strings like 'SUSE Linux Enterprise Server 15 SP6' to 'sles-15.6'
  • add SLESDefaultDriverVersionsMapper to select driver versions
    • SLES 15 SP6/SP7 -> driver 7.0.2 (ref: https://repo.radeon.com/amdgpu-install/7.0.2/sle/)
    • SLES 15 SP5 -> driver 6.2.2 (ref: https://repo.radeon.com/amdgpu-install/6.2.2/sle/)
  • register both 'sles' and 'suse' identifiers in mappers

• 0170a9a - add SLES Dockerfile template (DockerfileTemplate.sles) for building AMD GPU drivers on SLES (currently, I've skipped adding the GIM Dockerfile template for SLES, will tackle it once this goes through).

  • also embed the template via go:embed and add SLES case logic

• c2dce44 - docs: update example/deviceconfig_example.yaml <- dropped

• 4da60d3 - use "registry.suse.com" as the default base image registry if OS == "sles"

  • although, use-specified BaseImageRegistry still takes precedence
  • also extend tests in internal/kmmodule/kmmodule_test.go to test above changes in resolveDockerfile func

Test Plan

• b625441 - tests: update internal/utils_test.go for added support for SLES 15 SP*

Test Result

• truncated output of make unit-test after new added tests in b625441

  > make unit-test
