[KeyVault] Get-default-policy returns gibberish in Python2

[tjprescott]

When I run get-default-policy on Python 2 many of the fields are filled with gibberish such that I can't immediately turn around and use it to get a self-signed cert:

{
  "issuerParameters": {
    "name": "U2VsZg=="
  },
  "keyProperties": {
    "exportable": true,
    "keySize": 2048,
    "keyType": "UlNB",
    "reuseKey": true
  },
  "lifetimeActions": [
    {
      "action": {
        "actionType": "AutoRenew"
      },
      "trigger": {
        "daysBeforeExpiry": 90
      }
    }
  ],
  "secretProperties": {
    "contentType": "YXBwbGljYXRpb24veC1wa2NzMTI="
  },
  "x509CertificateProperties": {
    "keyUsage": [
      "cRLSign",
      "dataEncipherment",
      "digitalSignature",
      "keyEncipherment",
      "keyAgreement",
      "keyCertSign"
    ],
    "subject": "Qz1VUywgU1Q9V0EsIEw9UmVkbW9uZCwgTz1Db250b3NvLCBPVT1Db250b3NvIEhSLCBDTj13d3cuY29udG9zby5jb20=",
    "validityInMonths": 12
  }
}

When I run on Python3:

{
  "issuerParameters": {
    "name": "Self"
  },
  "keyProperties": {
    "exportable": true,
    "keySize": 2048,
    "keyType": "RSA",
    "reuseKey": true
  },
  "lifetimeActions": [
    {
      "action": {
        "actionType": "AutoRenew"
      },
      "trigger": {
        "daysBeforeExpiry": 90
      }
    }
  ],
  "secretProperties": {
    "contentType": "application/x-pkcs12"
  },
  "x509CertificateProperties": {
    "keyUsage": [
      "cRLSign",
      "dataEncipherment",
      "digitalSignature",
      "keyEncipherment",
      "keyAgreement",
      "keyCertSign"
    ],
    "subject": "C=US, ST=WA, L=Redmond, O=Contoso, OU=Contoso HR, CN=www.contoso.com",
    "validityInMonths": 12
  }
}

(env) C:\Users\trpresco\Documents\github\azure-cli>az keyvault certificate get-default-policy
{
  "issuerParameters": {
    "name": "Self"
  },
  "keyProperties": {
    "exportable": true,
    "keySize": 2048,
    "keyType": "RSA",
    "reuseKey": true
  },
  "lifetimeActions": [
    {
      "action": {
        "actionType": "AutoRenew"
      },
      "trigger": {
        "daysBeforeExpiry": 90
      }
    }
  ],
  "secretProperties": {
    "contentType": "application/x-pkcs12"
  },
  "x509CertificateProperties": {

  }
}

Well... this is dumb. I'm simply returning an instance of a model class and the serializer is returning what looks to be base64 encoded strings.

@tjprescott we should have a label of python 2 vs 3 silliness.

[tjprescott]

I fixed it in my current PR by converting strings from: 'my merry string' to u'my merry string'. This causes the desired behavior on Python 2 and 3 (and I agree, it is dumb.)

Wanna add this too?

    def _test_keyvault_certificate_get_default_policy(self):
        result = self.cmd('keyvault certificate get-default-policy')
        self.assertEqual(result['issuerParameters']['name'], 'Self')
        self.assertEqual(result['secretProperties']['contentType'], 'application/x-pkcs12')
        subject = 'C=US, ST=WA, L=Redmond, O=Contoso, OU=Contoso HR, CN=www.contoso.com'
        self.assertEqual(result['x509CertificateProperties']['subject'], subject)

[tjprescott]

Yup. Also added similar checks for --scaffold since it is a different code path.
