SERVER-32198 Split CollectionShardingState::getMetadata into three methods
o getCurrentMetadataIfKnown - which returns the current filtering
metadata if any is available
o getMetadataForOperation - which returns the metadata which is required
by the current opertion, based on the OperationShardingState
o getCurrentMetadata - which returns the currently available filtering
metadata (or UNSHARDED if not known)
This is in preparation for making
getMetadataForOperation/getCurrentMetadata throw
StaleShardVersion exception if the metadata has not been loaded yet.
