[code-quality] W0602 global-variable-not-assigned

[Josh Powers]

Hi,

I have code similar to [1] where instead of directly assigning a dictionary
global variable the dictionary method update is used. Right now this
results in a W0602 global-variable-not-assigned.

Is this expected behavior and if so is there a better way to write the
above?

The actual code giving me this message is in cloud-init [2].
