Sample - azure_attestation

Issue description

When running the Azure Attestation server, the server never starts up insead crashes with an error (error attached at the bottom)

From my trace:

• Certificate is created
• Crash occurs on CreateAzureAttestationToken
  • In this function gash is calculated on the certificate
  • Errors out on GetRemoteReport(hash[:])

I also tried to establish my own AZURE attestation service and replacing the url in the example with the same result.

To reproduce

Steps to reproduce the behavior:

1. Run server as per the readme
2. Wait for error

Expected behavior

1. Run server
2. Server starts listening on 8080

Hi, you need to set "pccs_url" in /etc/sgx_default_qcnl.conf to "https://global.acccache.azure.net/sgx/certification/v4/"
