Tectonic makes internet requests on every invocation

[ilyapopov]

After recent commits, tectonic now makes multiple internet requests on every invocation, which has noticeably slowed down its startup time (even on a fast connection).

I am not sure of the nature of these requests (is it checking that the bundle is up to date?)

I would like to have a mode where no requests are made unless there is a missing package to be downloaded.

There is --only-cached but that one disables downloading completely, I understand.

I second that observation. In particular, it makes connections to 20.49.104.33:443, which seems to be an MS owned IP-address with no PTR record.

I assume thats related to #977
