Extend the Applier interface's Apply method with an optional
options parameter.
For the container image encryption we intend to use the options
parameter to pass image decryption parameters ('dcparameters'),
which are primarily (privatte) keys, in form of a JSON document
under the map key '_dcparameters', and pass them to the Applier's
Apply() method. This helps us to access decryption keys and start
the pipeline with the layer decryption before the layer data are
unzipped and untarred.

This change no longer requires the use of a UtlityVM on Windows to convert the
layer tar to an ext4 vhd for LCOW. This has a significant performance boost
that makes linux/amd64 layer extraction comparable to native Linux performance.
