Pinging @elastic/ingest (Project:fleet)

Dependencies added:

antlr4: 👍
oklog/ulid: 👍

urso/ecslog: Please update to recent ecslog. The one you are vendoing is older and still contains some bugs. The update will bring in urso/diag, urso/diag-ecs, and urso/sderr (functinoality has been split up). The testing with these is much improved and minor bugs and stability issues have been fixed.

hashicorp/errwrap: Do we need this? We already have github.com/pkg/errors which provides Wrap function.

hashicorp/go-multierror: Do we need this? We already have go.uber.org/multierr

Ecslog (functionality has been moved to sderr) provides functionality from multiple error packages in one package only. Plus it is compatible to the recent Go2 proposal (pkg/errors is deprecated and unmaintained), supports multiline printing via %+v and integrates well into ecslog.

[ph]

I will update ecslog since this should not have any impact on our code but for errwrap and multierror I will make a followup. I don't want to do refactor and merge on master at the same time.

errwrap is not used so we might clean this up, but go-multierror is used and i would keep it there and address later outside of this PR. To keep migration simple.

@urso dependecies updated and errwrap removed.

Looks like govendor did mess with you :)

@urso You have no idea how I hate that tool.

For me the tool just hangs for some projects I want to update. tried on windows/linux/mac, with new gopath... So I sometimes resort to update the json by hand. No idea who is more lucky :P

Both of us are not, I am not even sure if god mod will fix all theses problems.

Anyway, I've fixed the dependencies related to ecs.

merging failure aren't related to this change.
