[ASTERIXDB-3229][COMP] Part 3: Pass pushdown info to runtime
- user model changes: no
- storage format changes: no
- interface changes: yes
Details:
- Remove deprecated pushdown classes
- Use the new value-access pushdown processor which
utilizes the def-use chain.
- Separate IProjiectionFiltrationInfo for internal
and external datasets.
Interface changes:
- IProjectionFiltrationInfo:
- Made more generic to accomidate external and
internal datasets requirements
- Expose print() to print the pushdown info
in the query plan
- IMetadataProvider.java
- Remove meta() pushdown info as a result of
isolating internal and external IProjectionFiltrationInfo
