GraphClient failed requests questions

[FingerlessGlov3s]

I'm running parsedmarc against a M365 Mailbox via graph and every now and then (every 1-2 days), a request to graph fails and it fails with Max retries exceeded Remote end closed connection without response. I've had a look at the code and the graph sdk and far as I can tell it only tries once. This also lines up that I can only see 1 request made to graph.microsoft.com when I look at the HTTP proxy (squid) I'm using. When it fails the parsedmarc process exits and has to be started again by systemd.

I've added these 2 parameters, to the GraphClient in mail/graph.py, not 100% if this will help but time will tell.

client_params["max_retries"] = 3
client_params["retry_backoff_factor"] = 0.8

Just wanted to make sure this approach is right and whether this could be added in the next offical release.
