Hi. You are likely already familiar with this rant, i and probably many many user prefer having stuff organized per XDG conventions with clean home and nothing there besides own folders, .config, .local and .cache.

I ask to add secondary ~/.config/docker-java/configuration.properties or a similar path to the lookup in DefaultDockerClientConfig.createDefaultConfigBuilder(). This doesn't require full XDG convention spec support, but is still better than the current situation, and since the file is read-only, there's no real harm attached, except maybe for complex override situations (use env var to point to different sources, having ~/.config/... as the default) - but these overrides aren't available as of now too. The request for additional docker-java directory stems from the same headache of thousand unorganized configuration files in a single directory.

This is a request for an extra source, not replacing existing one. There is no problem with backward compatibility, primary source would be read as of today, nothing bad will happen from it.
