Remove high level tasks

See #128 for details:

• Removes the DockerCleanupTask (might be replaced with a custom plugin, similar to the de.europace.docker-publish plugin)
• Removes the DockerPublishTask (the de.europace.docker-publish plugin might be a good alternative)
• Removes the DockerContainerTask (should be replaced with a custom plugin, similar to the de.europace.docker-publish plugin)

Bump docker-client, migrate to Property based config

We're working on stronger types while trying to keep everything as flexible as possible. This and the following releases might require changes in your build scripts. Please watch out for properties and methods being deprecated. Groovy DSL based Gradle scripts might require less changes than Kotlin DSL based Gradle scripts.

See the https://github.com/gesellix/gradle-docker-plugin-example repository for changes related to the Property based plugin and task configuration.
