Description

We wanted to support reading 1.x tables in 0.16.0 reader. 

Either entire timeline will be in 0.x or in 1.x. So, lets design a HoodieDefaultTimeline to be able to parse either timeline based on table version. We could define Hoodie0.xDefaultTimeline and Hoodie1.xDefaultTimeline and internally(w/n HoodieDefaultTimeline) to delegate to either of them.
