Fix Snowflake adapter warnings + add more debug logs

[ValeriyWorld]

Warning fixes:

1. Dependency warning related to snowflake-connector-python package.
2. Pydantic warning related to Pipe class - it had attribute schema, the same name was used in parent class BaseModel that had method with the same name (it is deprecated though, but still not deleted).

Debug logging enhancement:

1. Added logger.debug() messages in the mapping functions, which are useful to understand exactly where the collector crashed.
   
   Error case:
   
2. Due to avoid logging duplication (current mapping logic have some nesting logic) - changed properties to the methods decorated with @ttl_cache.

Tests updates:

1. Updated tests with new adapter and client realisation + added a few pipes to the test.
2. Added Snowflake tests to our run-tests workflow.
