DevServices: logs too verbose

[FroMage]

I just started an app with DevServices and I got this logorrhea:

2021-04-02 09:39:53,979 INFO  [org.tes.doc.DockerClientProviderStrategy] (build-4) Loaded org.testcontainers.dockerclient.EnvironmentAndSystemPropertyClientProviderStrategy from ~/.testcontainers.properties, will try it first

2021-04-02 09:40:01,655 INFO  [🐳 .6.12]] (build-4) Container postgres:9.6.12 started in PT5.830455S

I'm pretty sure that this should be enough:

2021-04-02 09:39:56,599 INFO  [🐳 .6.12]] (build-4) Starting DevServices [postgres:9.6.12] using docker [localhost]: 3e77926f877410807a40fb18872211ae659f76c602aac51aa30891cb7c8950bf

The rest is useless, no?

I have come up with a fix where the log messages are displayed on the status bar at the bottom, so the user still sees progress, then disappear once the container is up.

If startup fails the messages are dumped.
