Simple update resource migration to Terraform Plugin Framework

[rounak-adhikary]

• Migrated simple_update to tpf framework
• simple_update is now action based, it will be recreated for anything substantial. The update operation is dummy.
• Relaxed cyclometric complexity from 10 to 20. It was giving error for PowerOperation and updateRedfishSimpleUpdate methods, which, IMHO, isn't too complex.
• Added in golanci-lint the skipping of unmigrated files inside redfish folder as the report seemed too cluttered. The expectation is that whenever new files from that directory is migrated, the developer re-enables linting for those files.
  Removed user and virtual media entries to avoid confusion.
