More explanation on model deployment CLI command

[jorritsandbrink]

It would be helpful if the model deployment step could be explained in more detail. Currently the doc (https://github.com/Azure-Samples/MLOpsDatabricks/blob/master/docs/release-pipeline.md) only says that the model should be deployed with the CLI command
az ml model deploy
but it gives no further indication on the exact configuration of this command (e.g. which paramaters to use and with which values).
