Docs: Move from CloudCopy --> AzCopy

[SeanKilleen]

AzCopy is Microsoft's tool for copying files to Azure storage blog.

I think the Azure PowerShell tools unfortunately mostly support copying between blobs.

As of now, I recommend this instead of Azure PowerShell tools.

Build Server Changes

• Move Azure Storage Tools into the tools directory

Code Changes

• Understand current syntax of build process for copying items using AzCopy
• Replace CloudCopy call with a command-line call to AzCopy

Testing

Not sure I can really help out with this one since it has to be done on the build server. I'll do my best to launch the command locally and at least ensure that it fails in an understandable way.

@SeanKilleen if we can make this work with a local copy of the AzCopy binary, per #819, then that'll make life a lot easier all around :p

[SeanKilleen]

@Aaronontheweb 100% agreed, already put that into #819 for that exact reason. Wasn't thinking it through during my initial write-up.

[Aaronontheweb]

Still have some bugs I need to sort out with AzCopy - setting right content-headers and such.

[SeanKilleen]

@Aaronontheweb sorry that I don't have more visibility into what you're seeing. If you want to post a little more about it here (error messages, general background, etc.) I can try to do some legwork on it.

[Aaronontheweb]

no error messages - just not seeing the results I expect inside Azure blob storage.

Saw two problems basically:

1. Some content didn't look like it was being overwritten correctly (replacing an existing blob with a local file from source)
2. Uploaded content had the incorrect MIME type

Just closed a PR that fixes problem 2 - going to see if the issue with problem 1 was related to something else I was doing last night.

[Aaronontheweb]

@SeanKilleen turns out that the content not being overwritten correctly is an Azure CDN issue... I need to find a way to set a better default content-cache expiration header.

Might just disable the CDN for now and serve everything directly from blob storage.

[Aaronontheweb]

But otherwise, everything else is working.

[Aaronontheweb]

In order to use this with the CDN we'll need to be able to tell AzCopy to do this for each file: https://msdn.microsoft.com/en-us/library/gg680306.aspx

Not a big deal though. We'll just disable the CDN for now.
