Commit 57577846a75c23d8d247e9f05f76a57d353d400d in asterixdb's branch

[ASTERIXDB-2933][COMP][EXT] Pushdowns Part1: Expected Schema Node
- user model changes: no
- storage format changes: no
- interface changes: no
Details:
We want to have a more aggressive pushdown for Parquet. To do so,
we need to compute the expected schema from the expressions in the
query plan. This change introduces the data structure that holds the
expected schema information.
Note:
Moved from asterix-om to asterix-algebra as the expected schema should
not be exposed outside the compiler.
