Persist docker deployment infos to a file in the current directory

[fmhoeger]

When deploying via docker important information is written to the console (STDOUT) at the end of the deployment process. This includes the URL of the deployed experiment, the credentials to log into the dashboard as well as info for how to access the logs.

Unfortunately, all this data is lost when closing the terminal window, e.g. unintentionally, unless it has been manually copied into a file before.

We want the deployment information as described above to be automatically written to a file in the current directory.
