Disable attention plot with a command line parameter

See original GitHub issue

Describe the bug I’m training on clusters, but the machines don’t have libpng installed. Since I don’t really need the attention plot, I want to just disable the plot. However, I cannot find a way to disable that.

To Reproduce Steps to reproduce the behavior:

run the librispeech recipe on a machine without libpng
