net: refactor self=this to arrow functions
Affected core subsystem(s)
net
Description of change
Refactor unused self=this
code to code without without this pattern
making it more consistent with the rest of our code.
There were PRs to do this code-base wide but they all seem to have stalled so I figured I'd do this in the least objectionable way one change at a time.
