Add optional timeouts for project managers

[gregorymacharia]

On a previous incident occurring due to a disruption in npmjs.org, there were very long response times (~60s) that ultimately came back with 503 responses. This impacted Terrapin's latencies and availability. This change allows users to specify timeouts when they use OSSGadget's project managers when they call CreateProjectManager

Seems like a fine change to make, though not clear to me that the tests here are actually exercising the timeout functionality itself to confirm its working which should be possible by mocking the request as a sleep.

Makes sense I will add another commit to mock a delay and add to those tests

With the test to confirm timeout functionality I think this LGTM.
