[bin][installdumux] Use logger to print to file and stream simultaneouly and add progress symbol
(1) Prints simultaneously to stream and file. The terminal only shows info messages warnings and errors while the file also contains debug output in addition. Before some output was in the file and some in the terminal which made it difficult to inspect the log file.
(2) I also added a progress spinner that gets displayed while a command is running.
The initial suggestion for (1) came from @gruenich in !3615 (closed). I added a thank you note in the commit message.
