There is a plan to build an initial Oracle DB connector

[izgeri]

Overview

Based on the additional info provided in #1162, work to see if the available info is sufficient to get e2e with an initial / alpha oracle connector.

Definition of done

• Validate that you are able to get a working local environment up using the Oracle Express Edition (see Secretless has an Oracle DB connector #1162 for more info) - document the requirements to get your environment working in a comment or in a branch referenced in a comment on this PR.
• Review the available oracle DB libraries referenced in Secretless has an Oracle DB connector #1162 and document as a comment on this issue a plan to build an oracle connector starting from the tcp template. The initial connector can be as simple as possible - no need to support TCP for the secretless-to-oracle connection, its flow can just be to get the host/port/user/pass from secretless config and inject the credentials into the connection request from the client. If we can have a plan to get a very basic connector end-to-end using the available libraries, it will be a solid result.

To be clear, the outcome of this card is:

• A documented local development for Oracle (esp. including notes on leveraging wireshark and/or docker-compose)
• A documented plan for implementing an alpha Oracle connector
