Timeouts for pulling PRs from Enterprise Github

[dougtweedy]

We are seeing an issue with timeouts on multiple servers within our environment. It happens consistently throughout the day with an estimated failure rate of about 60%. Jenkins receives the hook correctly every time but when the PR builder attempts to pull the PR, it times out. When curling the endpoints, I don't see the same timeouts so I believe this to be an issue within the plugin itself. Below are details

Jenkins Version: 1.647 (also seen on 2.46.3)
Pull Request Plugin: 1.34 (also seen on 1.35 and 1.39)

Is there a place to set a timeout value?
