* First conversion
* Use serf 0.8.2 tag and associated updated deps
* * Move freeport and testutil into internal/
* Make internal/ its own module
* Update imports
* Add replace statements so API and normal Consul code are
self-referencing for ease of development
* Adapt to newer goe/values
* Bump to new cleanhttp
* Fix ban nonprintable chars test
* Update lock bad args test
The error message when the duration cannot be parsed changed in Go 1.12
(ae0c435877d3aacb9af5e706c40f9dddde5d3e67). This updates that test.
* Update another test as well
* Bump travis
* Bump circleci
* Bump go-discover and godo to get rid of launchpad dep
* Bump dockerfile go version
* fix tar command
* Bump go-cleanhttp
* Connect: Fix Envoy getting stuck during load
Also in this PR:
- Enabled outlier detection on upstreams which will mark instances unhealthy after 5 failures (using Envoy's defaults)
- Enable weighted load balancing where DNS weights are configured
* Fix empty load assignments in the right place
* Fix import names from review
* Move millisecond parse to a helper function
- the space after `=` is significant in sc parameters (binPath= "<path> <args>, start= auto)
- given the text "the service automatically starts up during/after boot", added `start= auto` to
the example, otherwise the service will be set to Manual start mode.
* Make Connect health queryies unblock correctly in all cases and use optimal number of watch chans. Fixes#5506.
* Node check test cases and clearer bug test doc
* Comment update
* Added a note to GCE auto-join credentials option
Simply added a note to remind users that putting a json file in the config-dir will make consul parse it as a config file.
Hope to help someone else avoid wasting a day because of these errors:
==> Error parsing /etc/consul.d/credentials.json: 10 error(s) occurred: * invalid config key private_key
* Updated according to style guidelines

Refs #4984.
Watching chans for every node we touch in a health query is wasteful. In #4984 it shows that if there are more than 682 service instances we always fallback to watching all services which kills performance.
We already have a record in MemDB that is reliably update whenever the service health result should change thanks to per-service watch indexes.
So in general, provided there is at least one service instances and we actually have a service index for it (we always do now) we only ever need to watch a single channel.
This saves us from ever falling back to the general index and causing the performance cliff in #4984, but it also means fewer goroutines and work done for every blocking health query.
It also saves some allocations made during the query because we no longer have to populate a WatchSet with 3 chans per service instance which saves the internal map allocation.
This passes all state store tests except the one that explicitly checked for the fallback behaviour we've now optimized away and in general seems safe.
