Move imagecache code from nova.virt.libvirt.utils

Browse Source 
The imagecache related code in libvirt.utils uses the base_dir_name
config option.

If we move the imagecache utils into imagecache, then we can move
the base_dir_name option into that module since there are no other
users of it.

Having all the imagecache code in the imagecache module seems like
a sensible thing to do anyway.
