Summary: The patch adds support for exposing the start of the expiration range for TTL blob files through the `GetLiveFilesMetaData` API. This can be used for monitoring purposes, i.e. to make sure TTL blob files are deleted in a timely manner. The patch also fixes a couple of uninitialized variable issues.
