Enable glance sparse image upload

To handle sparse image upload, new config parameters
``rbd_thin_provisioning`` and ``filesystem_thin_provisioning``
have been added in glance for rbd and filesystem backends
respectively with enabling image_conversion plugin for both
types of backends.

To make the above parameters enable, adding 'GlanceSparseUploadEnabled'
parameter in THT.
