v3.0.0-alpha0

Initial attempt at containerization. Lots of work to do still, but at the point it has some basic functionality:

• Extends smoothness docker template
• Can browse some pages
• Has an Oracle database connection (currently empty database)
• Has a Keycloak auth connection

Incomplete list of known issues:

• Conversion from legacy shared global users table to fetching from Keycloak incomplete
• Conversion from legacy shared beam destinations table to dedicated local table incomplete
• Email support not setup yet
• Need to replace configuration strategy from packaging a standalone.xml to a script of jboss-cli commands
• Need to replace configuration strategy from packaging a realms.json to a script of config commands
• Need to refactor help page more generically (use env instead of build-time context-params?)
• Docker image we extend from actually should be more generic - currently contains smoothness-demo.war!
• Need to refactor out even more common smoothness app configuration, docs, and scaffolding into upstream lib.
• Docker build with build.yml not caching well, requires --no-cache currently (need to COPY targeted individual source files?)
• Logout not working correctly currently (looks like config issue - using EXTERNAL "localhost" when should be using INTERNAL "keycloak")
• Add some test data to the test database
