Add command 'logs'

**Is your feature request related to a problem? Please describe.**

Sometimes an error happens in the entry-point of a toolbox. Currently the best way to debug these problems is to either attach to the start of a toolbox or look through the logs. These methods are both useful in different situations. To view the logs of a toolbox, the command `podman logs` can be used. The problem with the command is that it bundles all logs of a toolbox and does not distinguish between starts, thus it is hard to find relevant information inside.

**Describe the solution you'd like**

Have a command operating on top of `podman logs` and gives greater control over the presentation of the logs (e.g., choosing boot, formatting, highlighting of relevant parts,..)

**Describe alternatives you've considered**

Extending the upstream command.
