Stub Oracle database for localhost and CI testing

[patheard]

Investigate creating a stub Oracle database for use with localhost dev and CI automated tests.

Testing docker-compose env with:
https://github.com/wnameless/docker-oracle-xe-11g.git

Created example docker-compose service:

Currently hitting a character set problem. The dev/prod service is using the following Oracle with a character set of WE8MSWIN1252:

Oracle Database 11g Enterprise Edition Release 11.2.0.4.0 - 64bit Production
PL/SQL Release 11.2.0.4.0 - Production
"CORE    11.2.0.4.0    Production"
TNS for Linux: Version 11.2.0.4.0 - Production
NLSRTL Version 11.2.0.4.0 - Production

The docker image I'm using is Express Edition 11g 11.2 on Linux, which only supports UTF-8. This issue has more details: wnameless/docker-oracle-xe-11g#96

Unit tests in CI are now running against stubbed database.
