update booster parent and Swarm to latest releases (#19)
update booster parent and Swarm to latest releases (#19)

This commit also removes an explicit `<include>`
of the `wildfly-swarm-health-check` enricher.
This is because:

- Including it is no longer necessary, latest booster
  parent prescribes Fabric8 Maven plugin 3.5.22 which
  applies this enricher automatically by default.
- An explicit include also changes order of enricher
  application. If a health check enricher is applied
  before an enricher that generates default `deployment.yml`,
  the health check isn't actually added at all. Which
  is exactly what happened here.
