Wildfly runtime prototype

[awisniew90]

Still to do (among many things):

1. Change context root from default app name
2. JDBC Booster - flesh out cli commands to add datasource and drivers
3. General cleanup and more refactoring as needed.

Key Points:

1. Installs wildfly to target dir
2. Uses wildfly CLI (jboss-cli.sh) for configuration / app deployment / stopping server
3. Uses standalone.sh invocation for start and run
4. New wildfly booster that can be added to use wildfly runtime
5. One set of general "BoostMojos" that will detect runtime and then call either the Liberty or Wildfly mojos
6. Two sets of Booster Configurators (for Liberty and Wildfly).

Discussion:

1. Default port is Port 8080. Should this be 9080 for Boost?
2. Mojo rerouting - Do we want to do this differently?
3. Booster Configurator refactoring - Do we want to do this differently too?
4. How do properties look in all of this?

The refactoring done here is just one of probably a dozen ways we can do this. We should discuss and see what our best option is.
