Bump go-discover to support EC2 Metadata Service v2 (#6865)
Refs https://github.com/hashicorp/go-discover/pull/128

* deps: add replace directive for gocheck

Transitive dep, source at https://launchpad.net/gocheck indicates
project moved. This also avoids a dependency on bzr when fetching
modules. Refs https://github.com/hashicorp/consul/pull/6818

* deps: make update-vendor

* test: update retry-join expected names from go-discover
