1) Simplify the explicit plan handling between the parser and the engine. It makes no sense to pass the join type as it's ignored internally.
...
2) Support hash joins in the plan output and in the parser. For the latter, it's just the syntax sugar, same as loop vs merge join (see above).

Refactor DSQL, continuing the work I started in 2.5:
...
- Renamed CompiledStatement to DsqlCompilerScratch and removed inheritance to dsql_req.
- Introduced DsqlCompilerStatement, moving things from dsql_req - not completelly shareable yet.
- Make dsql_req reference a DsqlCompilerStatement. DsqlCompilerScratch may be discarded in the future.
- Replaced AlterCharSetNode usage by PreparedStatement for the default collation in database creation.
- Changed METD API.
