// HACK(chrboum): This method is a hack.  It was written to work around this issue
// (https://github.com/Azure/azure-sdk-for-go/issues/307) and to an extent this
// issue (https://github.com/Azure/azure-rest-api-specs/issues/188).
//
// Capturing a VM is a long running operation that requires polling.  There are
// couple different forms of polling, and the end result of a poll operation is
// discarded by the SDK.  It is expected that any discarded data can be re-fetched,
// so discarding it has minimal impact.  Unfortunately, there is no way to re-fetch
// the template returned by a capture call that I am aware of.
//
// If the second issue were fixed the VM ID would be included when GET'ing a VM.  The
// VM ID could be used to locate the captured VHD, and captured template.
// Unfortunately, the VM ID is not included so this method cannot be used either.
//
// This code captures the template and saves it to the client (the AzureClient type).
// It expects that the capture API is called only once, or rather you only care that the
// last call's value is important because subsequent requests are not persisted.  There
// is no care given to multiple threads writing this value because for our use case
// it does not matter.
