Rename `TableProperties.WRITE_NEW_DATA_LOCATION` to `TableProperties.FOLDER_STORE_PATH`

`TableProperties.WRITE_NEW_DATA_LOCATION` represents a config setting of `write.folder-storage.path`. 
`TableProperties.OBJECT_STORE_PATH` represents a config setting of `write.object-storage.path `

Renaming `TableProperties.WRITE_NEW_DATA_LOCATION` to `TableProperties.FOLDER_STORE_PATH` makes the code much easier to read, and more clearly articulates the configuration setting.
