'Certificate path doesn't exist' when using DOCKER_HOST=unix:///var/run/docker.sock #480
Description
Switched to 3.0.0-RC1 after #419 was fixed
But now the config builder fails with setting
export DOCKER_HOST=unix:///var/run/docker.sock
DockerClientConfig.createDefaultConfigBuilder().build()
com.github.dockerjava.api.exception.DockerClientException: Certificate path (DOCKER_CERT_PATH) '/var/lib/jenkins/.docker/certs' doesn't exist. (DockerClientConfig.java:112)
[error] com.github.dockerjava.core.DockerClientConfig.checkDockerCertPath(DockerClientConfig.java:112)
[error] com.github.dockerjava.core.DockerClientConfig.<init>(DockerClientConfig.java:85)

[error] com.whisk.docker.DockerKit$class.$init$(DockerKit.scala:10)
Am I correct that for sock communication there is no need for the certificate path check? At least on 2.x this used to work.
