[nis] v0.6.102

Added

• add new NEM testnet
• add 'beneficiary' and 'totalFee' to the result from /local/block/at to determine the block beneficiary directly
• add route /mosaic/definition/last to get the last mosaic definition
• add local endpoint /local/mosaic/definition/supply for querying historical mosaic supplies, including expiration height
• add a new TRACK_EXPIRED_MOSAICS node feature to track expired mosaics
• add /local/mosaics/expired to report expired mosaics, and include a new 'expiredMosaicType' property in the output to differentiate expired and restored mosaics

Changed

• mosaic description change would effectively zero all balances before mosaic redefinition fork. Update MosaicDefinitionCreationObserver to track these balance resets as mosaic expirations
• replace removeAll with removeExpiration in ExpiredNamespacesObserver

Fixed

• only 'restore' mosaic balances if the root is inactive
• MosaicDefinitionRetriever needs SQL parameters
• block lessor is not set correctly in the database when (future) remote link is pending. Update RemoteLinks to retrieve the active (not current) remote link
