Change timeout value used to detect if docker is available

Hi,

I would to decrease the timeout value used to detect if Docker is available. Is it possible to change this timeout by configuration ?

2021-09-01 17:17:35,642 [main] INFO org.testcontainers.dockerclient.DockerClientProviderStrategy - Loaded org.testcontainers.dockerclient.NpipeSocketClientProviderStrategy from ~/.testcontainers.properties, will try it first
2021-09-01 17:18:06,494 [main] INFO org.testcontainers.dockerclient.DockerMachineClientProviderStrategy - docker-machine executable was not found on PATH ([])

#4386 should do this 😄

Unless you're looking to limit the total time spent trying to find docker; #4386 will achieve this indirectly, pretty much, but we don't have plans to set a total time limit.

With the property "client.ping.timeout", that's exactly what I'm looking for. 👍
