> This is a reland of 260688, which is reverted due to false charge of build failure.

> Previously, we used FileEntry.getMetadata() to retrieve filesystem metadata and getDriveEntryProperties() to get Drive metadata, so we need 2 calls for 1 file on Drive.
> 
> With this patch, getDriveEntryProperties() returns not only Drive metadata but also filesystem metadata. It's enough to call only getDriveEntryProperties() and we can reduce a number of calls by half.
