* change the UnsafeAppend to Append

* fix buffer builder in shuffle

shuffle builder use UnsafeAppend API for better performance. it
tries to reserve enough space based on results of last recordbatch,
this maybe not buggy if there's a dense recordbatch after a sparse one.

this patch adds below fixes:
- adds Reset() after Finish() in builder
- reserve length for offset_builder in binary builder

A further clean up on the reservation logic should be needed.

* Delete cache by adding a release in InMemoryRelation

Since unpersist only delete RDD object, seems our deAllocator wasn't being called along
Now we added a release function in InMemoryRelation clearCache() func, may need to think
a new way for 3.1.0
