Allow user to print all logs from a specific date.

Moved *class logs* to separate file (lib/shelly/cli/logs.rb). Splited logs into two commands:
* `shelly logs latest` - this is copy of previous `shelly logs` which allows user to print latest logs.
* `shelly logs date [DATE]` - which allows user to print all logs from a specific date.
