> Now that HDFS-6584 feature is ready and supports block storage policies on both files
and directories, we can make use of Storage Policies to store the LAZY_PERSIST preference.
> This only affects how the preference is persisted in the FsImage/Edit logs. There is
no change to the client API or to NN-DN interaction.
