Possibility to increase the log level

[eisemakr]

As I had problems with the initial setup of semaphore on my Ansible environment, it would have been super helpful if semaphore could log to the console or to the logs the exact ansible command which it is submitting.

The debug mode from semaphore only does show advanced ansible output, but if that does not fit the output of ansible cli debugging of the setup is hard.

Maybe the possibility to increase the loglevel of semaphore itself would be a good feature in the future.
