Add Azure Blob Sync

@sebastianfeldmann : I am not sure if I have modified everything correctly for the ant task to build the phar package.

Test

List containers in storage account : none

$ az storage container list --connection-string 'xxxxxxxx' --subscription xxxxxxx
[]

List local backup generated : none

$ ls backup/

Configuration : tar local folder htdocs and upload it to mycontainer on Azure at path backup/ with remote cleanup by quantity (keep 2)
