Add ignore_transactions config to disable transaction operations

[jayantsing-db]

Introduces a new ignore_transactions configuration parameter (default: True) to control transaction-related behavior in the Connection class.

When ignore_transactions=True (default):

• commit(): no-op, returns immediately
• rollback(): raises NotSupportedError with message "Transactions are not supported on Databricks"
• autocommit setter: no-op, returns immediately

When ignore_transactions=False:

• All transaction methods execute normally

Changes:

• Added ignore_transactions parameter to Connection.init() with default value True
• Modified commit(), rollback(), and autocommit setter to check ignore_transactions flag
• Updated unit tests to pass ignore_transactions=False when testing transaction functionality
• Updated e2e transaction tests to pass ignore_transactions=False
• Added three new unit tests to verify ignore_transactions

Hey @vikrantpuppala, just an FYI, when the flag is set to false, the autocommit getter will return true. I wasn’t entirely sure which default made the most sense, but true seems more appropriate. Airflow jobs shouldn’t break with this behavior, but could you double-check as well? I’ve already verified on my end.
