Bug#1038383: lsb_release: please add the ability to guess_release_from_apt()

[Harshula]

Package: lsb-release
Version: 12.0-1
Severity: important
Hi Gioele,

The old lsb_release.py script contains the function 
guess_release_from_apt(). Can you please add similar functionality to 
lsb-release to fix the regression?

Thanks,
Harshula
