Add test for retry token expiration

[gretchenfrage]

Now that #2089 is merged, we should add a test for Retry token expiration. One could start by modifying this test:

quinn/quinn-proto/src/tests/mod.rs

Line 186 in bfbeecd

fn stateless_retry() {

Hi @gretchenfrage, could I take a look at this issue and start working on it?

I plan to write a test to cover the following branch by using TimeSource trait.

quinn/quinn-proto/src/token.rs

Line 60 in f5b1ec7

if retry.issued + server_config.retry_token_lifetime < server_config.time_source.now() {

Go ahead!

In a PR I have in-progress, #1912, I create a FakeTimeSource implementation of TimeSource and use it to test the expiration of a different kind of token that that PR also introduces. You're welcome to copy/paste that FakeTimeSource code into a branch you create if you think that's the best way to create your test.

Thank you for the information!
It seems that new test cases may need to use the IncomingBehaviour enum. I noticed that #1912 modifies this enum and TestEndpoint. To avoid conflicts, I’ll wait for your PR to be merged before submitting mine.
