Review conditions on auto-configuration

[bclozel]

The current auto-configuration has @ConditionalOnClass(DockerClientProperties.class).

Since this properties class is part of the same package, this condition always return true. Did you mean to do that on a library class like DockerClientBuilder ?

I have improved it now. Could you give me more suggestions?

Conditions look good now - I see that you're working against two different DockerClient APIs - separating the configurations was a good choice here.

Thanks!
