Replace print method with logging module

[raukadah]

While looking at the code base it appears that for each info printed to user is derived from print statement. We can replace it with logging module.

[raukadah@ironman genpass]$ git grep 'print'
password.py:        print("No records found")
password.py:        print(table)
password.py:        print("No records found")
password.py:        print("No records found")
password.py:        print("No records found")
password.py:        print(spass)
