Secrets PR 6 - Update Oracle properties (#18320)

* Add SSL keystore and truststore secret properties to Oracle driver YAML files


Update Oracle driver to set keystore and truststore connection options from secret values

Adding new `select-keys-sequentially` helper function for dealing with assertions on transformed conn props

Add new function to the secret namespace to return a lighter weight "secret map", and remove that functionality from the `handle-db-details-secret-prop!`, so that it can be reused from connection testing

Modifying CircleCI to set the corresponding truststore secret conn prop vars instead of JVM-level truststore settings, as the test had been doing previously

Expand Oracle test connection details to incorporate all SSL related properties, and also make it a function instead of delayed def (so changes can be picked up later)

Misc. fixes in Oracle driver YAML files

Update `exception-classes-not-to-retry` to include SSLHandshakeException

Fix misc issues in secret and database model code

Update CircleCI config to use correct secret based env var keys and values

Add *database-name-override* dynamic var in `metabase.test.data.interface` to allow for DB name overriding

Fix up ssl connectivity test so all parts pass successfully

Get rid of crazy with-redefs to swap in the existing test-data's schema, and instead, just dropping the DB if it was created under a different schema (similar to what H2 does)
