- Uniformed logs and diagnostics:
- Logging and adding to diagnostics is done by the highest level function (Create/Read/Update/Delete/Import) using `LogAndAddError`
- Lower-level routines' signature changed to return error instead of writing to diagnostics
- Standardize summary and details across services
- Removed manual adding of relevant variables to details (they're in the context, TF adds them to logs)
- Changed validators to be closer to official implementation
- Fix logging wrong output after wait
- Fix Argus checking wrong diagnostics
- Fix Resource Manager not updating state after project update
- Fix unnecessary pointer in LogAndAddError
