bug [azure]: dns zone API requests are not sanitized to remove changing request/trace ids

[mikenairn]

What

If there is an issue when listing zones the error returned is not sanitized to remove trace/request ids that change on every request. This is resulting in the error that is being added to the dnsrecord status changing on every repeated request and triggering this issue #218

Test added here should be enabled for Azure to reproduce the problem:

//Azure
Expect(testDNSProviderSecret.Type).To(Equal(v1alpha1.SecretTypeKuadrantAzure))
pBuilder.WithDataItem(v1alpha1.AzureJsonKey, "{\"tenantId\": \"1234\", \"subscriptionId\": \"1234\", \"resourceGroup\": \"foobar\", \"aadClientId\": \"1234\", \"aadClientSecret\": \"1234\"}")
expectedProviderErr = "ClientSecretCredential: unable to resolve an endpoint"
