Gagan Goel 60eb0f86ec MCOL-5021 non-AUX column files are opened in read-only mode during ...

the DELETE operation. ColumnOp::readBlock() calls can cause writes
to database files when the active chunk list in ChunkManager is full.
Since non-AUX columns are read-only for the DELETE operation, we prevent
writes of compressed chunks and header for these columns by passing
an isReadOnly flag to CompFileData which indicates whether the column
is read-only or read-write.
