core: add calculated discard fields for storage domain

This patch adds two fields for storage domains, calculated by a new
view, vg_discard_support_view:
1. supports_discard - true iff all of the luns that the storage domain
is built from support discard, i.e each lun's discard_max_size field is
greater than 0.
2. discard_zeroes_data - true iff all of the luns that the storage
domain is built from have their discard_zeroes_data = true.
