stop caching node state in Etcd 2021-02-24 17:19:27 -05:00

8d6f97604f use testhook to run server tests so we can have post-processing and audits 
This gives more consistency with the other tests and allows us to get audit
checks on the server/ tests. The tests on the clients being closed are
temporarily disabled because they tend to think the last test's clients
are "still open" for a few seconds after the test completes.

9333b1b27e leaseKeepAlive: manage context and shut it down cleanly 
Every usage of this just ran keepAlive func as a goroutine with a timer, using
a parent context, but the keepAlive func didn't know about that context, so
it couldn't use that context for its own messages or interactions. Change
it to create its own cancelable context from a provided parent, and use
that to control its inner behavior.

Note that we *do* still need to send the revoke at least sometimes -- otherwise
cluster states don't update correctly. But we can time that send out
rather than using context.Background(), because after a TTL's worth of time,
there's no lease to revoke anyway.

Also, add hooks for testhook tracking so we can confirm/deny that things
are getting shut down, which they weren't.

82a975fd2a avoid race conditions on nodes 
Turns out we sometimes modify returned nodes. Handle this better, but
also fix up some cases where we were generating node lists we didn't really
need to answer simple questions.

07a014e952 cache Nodes calls in EtcdWithCache 
The Peers() data is cached, but then every call still has to unmarshal JSON
and that's stunningly expensive. Let's not!
