Kelvin Zhang 05ff7055b6 Add spl-downgrade field to ota metadata 
In aosp/1581143 , we banned generation of SPL downgrade OTAs. However,
caller of OTA script can still force an SPL downgrade OTA by passing
--spl_downgrade flag. If this flag is specified, we propagate it to OTA
metadata so that GOTA server can properly honor this flag.
