Added Operator to transfer data from MSSql to Oracle, building on top of oracleToOracleTransfer operator.

• Description above provides context of the change
• Unit tests coverage for changes (not needed for documentation changes) -> Also needed for operator added? I dont see tests for all operators in the test folder
• Target Github ISSUE in description if exists -> none created, seems optional
• Commits follow "How to write a good git commit message"
• Relevant documentation is updated including usage instructions. -> should be auto generated, please let me know if I should provide documentation somewhere, I created an example Dag which uses my new operator, hope this is good aswell
• I will engage committers as explained in Contribution Workflow Example.
