Hello Mike Percy, Kudu Jenkins, Grant Henke, Todd Lipcon,

schema: add is_deleted virtual column
This patch introduces a very basic concept of a "virtual column", defined as
a static column with a name, type, and defaults. A Kudu subsystem that
wishes to interact with a virtual column needs to first figure out if the
projection includes it (via ColumnSchema::Equals()). When projected, the
virtual column's data will be entirely default; it's the subsystem's
responsibility to fill in something meaningful afterwards.
This first cut is hardly robust. It remains to be seen how usable this
bare-bones abstraction will be; so far it's sufficient for the MemRowSet.
