Fixed a lot of things:

• Redshift debug and sync — wasn't working if tables in public and schema not selected + sync had a pg_enum conflict with Ibis (fix nao sync doesn't work with redshift #146)
• Snowflake sync —
• Databricks sync — Certs issues
• Postgres sync

Reworked

• The sync command is now done differently, we got rid of the DataAccessor, there is only a template engine with function available, by default there are 3 templates that gives columns, descriptions and previews. Can be extended infinitely
• -p option in the sync CLI to run a specific provider or a sub database (fix Synchronize only one pice of context in nao sync #157)

Tests

• added a large test integration suite that run sync on every backend and check the whole output (can only be run if you have the correct .env file that I have) > next step might be to put this in the CI
