Ghanshyam Mann 0ba9e3a12e Fix gate by running l-c job on Bionic
l-c job template moved the l-c jobs running on Focal
and currently fails on many constraints.

Let's keep running l-c job on bionic as it was before and we
can move it to Focal once issues are identified and fixed.

- Fixing the hacking tests which are behaving differently between
< 3.8.0 (until Ubuntu Bionic) and 3.8.2 (Ubuntu Focal).

Squashing below review also
