Use go mod for github.com/hashicorp/go-bindata/go-bindata and
github.com/elazarl/go-bindata-assetfs/go-bindata-assetfs but use
`@master` to pull the latest master. These packages don't have release
tags so `@master` worksaround it.
Adding `-trimpath` to builds removes the local working directory from
the goroutine stack traces, which makes our builds more reproducible
and doesn't leak information about our local development workstations
or CI environment.
Some tests assert on numbers on numbers of servers, e.g.
TestHTTP_AgentSetServers and TestHTTP_AgentListServers_ACL . Though, in dev and
test modes, the agent starts with servers having duplicate entries for
advertised and normalized RPC values, then settles with one unique value after
Raft/Serf re-sets servers with one single unique value.
This leads to flakiness, as the test will fail if assertion runs before Serf
update takes effect.
Here, we update the inital dev handling so it only adds a unique value if the
advertised and normalized values are the same.
Sample log lines illustrating the problem:

This closes#7456. It hides the terminal when the job is dead and
displays an error when trying to open an exec session for a task
that isn’t running. There’s a skipped test for the latter behaviour
that I’ll have to come back for.
This closes#7454. It makes use of the existing watchable tools to
allow the exec popup sidebar to be live-updating. It also adds
alphabetic sorting of task groups and tasks.
