feat(canner): implement new data source canner

[grieve54706]

Summary

Support new data source Canner Enterprise. It provides the PG wire protocol, so we can connect it by following Postgres.

Connection info

• host: str
• port: str
• user: str
• pat: str
• workspace: str
• enable_ssl: bool, If true, will connect with HTTPS

Additional information

• Canner enterprise does not support CREATE TEMPORARY VIEW to get the schema for ibis. We need to build schema by dry-run.
• Canner enterprise does not support dry-run, so we have to query with a limit of zero
• The table and column comments are stored in another service of Canner Enterprise. We need to query them by GraphQL.
• Preparing Canner Enterprise to test is difficult, so we don't test this feature in the CI.
