Fixing archai/devops workflow

[luisffranca]

Description

requirements.txt

• Changed scikit-image version to match Python 3.6

upload.py

• Resource not found when uploading a model. Fixed by using update_status_entity();
• Node column in Azure Table was populated with the local machine's name, locking the workflow. Fixed by using update_status_entity()

runner.py

• All rows are getting skipped due to: skip for now until other quantization finishes on our node. Although the model is already quantized, the column is not set as true. Fixed by correcting the logic of quantization verification.
• When there's a conversion error (e.g. onnx to dlc), the next state of the Azure Table does not reflect that. It gets stuck on "quantizing" or other unrelated status. Fixed by adding error checks.

Changes

• Bug fix (non-breaking change which fixes an issue)
