Applying a diff release to ES7 indices fail

[zcqian]

Currently, the Syncer functionality used in BioThings Hub uses ES6 syntax in a lot of places to update metadata and mapping on the Elasticsearch index. This makes applying a diff release to fail.

Current workaround: use full releases only until this is fixed.
