Integration tests in database mode - add Oracle 12.1 JDBC driver directly into libs dir (#1399)

Stop downloading Oracle driver for Oracle 12.1 from Oracle proprietary repo as it's very unreliable,
and from time to time the dependency cannot be dowloaded. Issue: "Could not parse POM https://www.oracle.com/content/secure/maven/content/com/oracle/jdbc/orai18n/12.2.0.1/orai18n-12.2.0.1.pom Invalid byte 1 of 1-byte UTF-8 sequence."
