azureUpload doesn't provide usefull debug information

[clguiman]

I tried to use the azureUpload command for our CI, but I couldn't figure out what I set wrong. There's no usefull debug information.
Here's the groovy script: azure-devops/ci@90d0987
And here's the error:
http://devops-ci.westcentralus.cloudapp.azure.com/job/azure-credentials/job/jenkinsci/job/master/44/console

MicrosoftAzureStorage - Uploading files to Microsoft Azure
MicrosoftAzureStorage - Failed to upload any build artifacts to Azure Storage

The plugin should provide better logs.

It seems no files matching the name pattern can be found. I've created a PR to print more logs and improved the error message.
