  • persist statistics somewhere inside the execution engine (i.e., persist base table statistics in datafusion catalog?)
  • implement analyze command + executor to compute base table statistics

refactor(core): separate cost model and stat estimation (#209)
29647f2 
part of #195

* also refactors the adv-cost crate to purely support cardinality
estimation
* rewrite optimize input task to reduce dead code (which might have some
effect on the plan output?)
* use `cargo run -p optd-sqlplannertest --bin planner_test_apply --
--enable-advanced-cost-model` to experiment with the advanced cost model
