Add an option for the pool name.

I'm going to use this to distinguish between containers that were launched

Search images by name regex.
Use container names to manage the pool contents.
Give the tmpnb and proxy containers names.
Make tasks to follow the logs.
Container names is in "Names", not "Name".
Ensure the default pool name is valid.
I AM THE REGEX :star:
