Some values from DockerTemplateOptions.configBuilder are replaced in DockerComputeServiceAdapter

Issue description:
If I want to use advanced Docker configuration by providing DockerTemplateOptions.configBuilder(...), then some values are replaced (exposed ports, port bindings) by configuration from the DockerTemplateOptions configuration. This is wrong, because by providing the Config.Builder instance I say I want to use exactly this configuration.

Expected state:
If the Config.Builder instance is provided, then it's used directly (unchanged).

Suggested fix:
The condition block if (containerConfigBuilder == null) { should be extended.
