[ovs-dev] [RFC ovn 3/5] ovn-detrace: rename ovn-detrace to ovn_detrace.py

[Adrian Moreno]

For external python programs to be able to load ovn-detrace as a python
module easily, it should end in .py and should have underscores.

Move ovn-detrace to ovn-detrac.py and create a symlink with the old name
for backwards compatibility.
