Add --logfile <path> command option to CLI commands

[pileks]

Is your feature request related to a problem? Please describe.
Currently, our CLI outputs logs only to the console. We want to have the option of specifying a log file as a secondary output.

Describe the solution you'd like
Add -l, --logfile command option to our CLI commands which would output whatever is being recorded inside the console to a log file.

Describe alternatives you've considered

Additional context
A small additional win would be to allow the path to be optional, and to provide a default log file name.
