Snowddl

- `destroy` CLI action now adds option `--apply-unsafe` automatically. Option `--destroy-without-prefix` should still provide a sufficient protection from accidentally destroying everything on production.
- Dropping object types `ROLE`, `EXTERNAL TABLE`, `STAGE` is now considered "unsafe". Dropping `ROLE` prior to dropping other objects causes re-assignment of OWNERSHIP. Dropping `EXTERNAL TABLE` causes loss of associated meta-data (e.g. files, partitions), which cannot be restored easily. Dropping `INTERNAL STAGE` destroys all files in that stage.

- Use special exit code `8` when any errors occurred inside resolvers or converters. Previously it was returned as exit code `0`.
- If user role was dropped manually, it will now be re-created and re-granted to corresponding user automatically.

- Fixed `default_sequence` for table columns not being converted when using `singledb` mode.
- Fixed DEFAULT value not being applied properly when adding new columns using `ALTER TABLE ... ADD COLUMN`.
- Switched to another Snowflake Trial account.

- Ignore `TEMPORARY STAGES` created by another sessions. Such stages should not appear in `SHOW STAGES` output, but they do.

- Added `runtime_version`, `imports`, `packages`, `handler` for `PROCEDURE` object type.
- Added ability to set multiple columns for `returns` of `PROCEDURE` object type, now it is possible to define `RETURNS TABLE (...)`.
- Added initial `collate` support for `TABLE` columns.

- Added `packages` for `FUNCTION` object type. Now it should be possible to use fully utilize Snowpark, Python and Java UDFs.
- `SnowDDLFormatter` is now exposed as public object, if you want to use it for something other than SnowDDL.
