Add classes: Logic, App_t. Add journal loging support

Class Logic has only dbus callbacks implemetation (package-manager,
connman), beside it it's empty implementation.

Verification:
1) Build cert-checker with debug, and install on emulator.
2) Run cert-checker - do it in emulator UI console (not via ssh).
3) On other console in emulator UI run command:
   journalctl -f | grep cert-checker
   - to see the logs.
4) On third console turn on and off offline mode on device:
   /usr/sbin/connmanctl enable offline
   /usr/sbin/connmanctl disable offline
5) You should see logs from cert-checker in journal
6) Install any app to check if package-manager signal works in cert-checker:
   pkgcmd -i -t wgt -p /usr/share/widget_demo/go.wgt -q
7) Check if logs are present.
