Update vendoring and common; Allow the AWS backend to get credentials from its environment.

[tomwilkie]

If you give the VMs the right instance profile/role, they can authenticate to DynamoDB without having credentials on the command line.

Tested, works like a charm.

Had to fiddle with dep, and upgrade to 0.5.0, as client_golang, weaveworks/common and uber/jaeger-lib were conflicting.

@bboreham PTAL

[bboreham]

Why? I would expect master to be the default in a repo with no releases.

What I need here, in the file, is the reason for the constraint, and the conditions under which it can be removed.

[bboreham]

I've just tried removing it and everything else stays the same.

Please update the PR title and description to include all the material changes.

Since I want to update common too, I rebased and tweaked this.

The changes are:

• update Gopkg.lock to the format of dep v0.5.0
• Don't use full URL as metric label on unmatched path (Don't use full URL as metric label on unmatched path weaveworks/common#108)
• Raise default server timeouts from 5s to 30s (Raise default server timeouts from 5s to 30s weaveworks/common#109)
• Return errors when http/grpc servers exit. (Return errors when http/grpc servers exit. weaveworks/common#92)
• Expose jaeger metrics (Expose jaeger metrics weaveworks/common#114)
• Allow the AWS backend to get credentials from its environment. (Allow the AWS backend to get credentials from its environment. weaveworks/common#111)

Hmm, I thought GitHub would pick up my branch in this PR - master...aws-sts

[bboreham]

@tomwilkie let me know if you'd like me to push the rebase to your branch

[tomwilkie]

Sorry for the delay @bboreham; I didn't realise you wanted the change list from weaveworks/common too!

I've also removed the constraint you identified as superfluous and rebased.

I've updated the vendored Prometheus to bring in prometheus/prometheus#4436, better tracing spans in PromQL. This required a bunch of updates to vendored k8s, and some minor modifications.
