Some future patches will require specifying an lvol_store name when calling spdk_lvs_init(). This means that passing NULL for spdk_lvs_opts will no longer be an option. So add an spdk_lvs_opts_init() (similar to spdk_bs_opts_init) which will initialize a default value for the cluster size. While here, prepend an underscore to spdk_setup_lvs_opts, since this function is not part of the public SPDK API.
