[#208] Tell the user where the master key is stored.

Close #208. Similar to commit 5de2957 When the master key file is saved, a message is printed out on the terminal so that the user knows where the file is. Example of session: % pgagroal-admin master-key Master key (will not echo): Master Key stored into /home/luca/.pgagroal/master.key
