Before, the submitted jobspec for sidecar_task would pass
through 2 key validation steps - once for the subset specific
to connect sidecar task definitions, and once again for the set
of normal task definition where the task would actually get
unmarshalled.
The valid keys for the normal task definition did not include
"name", which is supposed to be configurable for the sidecar
task. To fix this, just eliminate the double validation step,
and instead pass-in the correct set of keys to validate against
to the one generic task parser.
Fixes#7680
Before, if the sidecar_service stanza of a connect enabled service
was missing, the job submission would cause a panic in the nomad
agent. Since the panic was happening in the API handler the agent
itself continued running, but this change will the condition more
gracefully.
By fixing the `Copy` method, the API handler now returns the proper
error.

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:
