[bind10-dev] Minor change to Python style guidelines

[Shane Kerr]

All,

Our "official" Python style guidelines are basically just to use the
Python style guidelines:

https://bind10.isc.org/wiki/CodingGuidelines

Jelte suggested that it might be nice to put the __init__() function as
the first method in a class. I didn't see anything in the Python style
about this, but I am not opposed to it.

Shall I add this as an extra guideline to our Python style?
