Subject: [PATCH] #18705: Reading mimetype information from web.config when
 saving blobs in Azure

These mimetypse settings are originally used by IIS itself to get the mimetype
of specific files on the file system. We also then use it in AzureFileSystem to
assign a mime type to the blob to make it comprehensive.

<system.webServer>
        <staticContent>
            <remove fileExtension=".ogg" />
            <mimeMap fileExtension=".ogg" mimeType="audio/ogg" />
     </staticContent>
</system.webServer>
