bitbake: bitbake: Add Azure Storage fetcher implementation

        Allows bitbake to fetch from an Azure Storage account.

        The fetcher submodule is compatible with the az:// URI protocol, its
        functionality is based on bitbakes wget fetcher, superior in performance
        to using a propietary tool like azcopy which can handle cloud storage
        account operations with more functionality (that we dont need in a fetcher)
	but less compatibility.

        A sample URI uses can be defined in the following way:
	SRC_URI = "az://<azure-storage-account>.blob.core.windows.net/<container>/foo.tar.xz"

        This fetcher can easily be used with PREMIRRORS and SSTATE_MIRRORS, e.g.:

        SSTATE_MIRRORS = "file://.* az://<azure-storage-account>.blob.core.windows.net/sstate-cache/PATH;downloadfilename=PATH \n"

        PREMIRRORS_prepend = "\
            git://.*/.* az://<azure-storage-account>.blob.core.windows.net/downloads/ \n \
            ftp://.*/.* az://<azure-storage-account>.blob.core.windows.net/downloads/ \n \
            http://.*/.* az://<azure-storage-account>.blob.core.windows.net/downloads/ \n \
            https://.*/.* az://<azure-storage-account>.blob.core.windows.net/downloads/ \n \
        "

        Can also be used with non-public access Azure Storage accounts/containers via a
        Shared Access Signature by declaring the AZ_SAS variable which will be
        automatically used by the fetcher:

        AZ_SAS="?sv=2000-01-01&ss=...&sig=somesignature"
