This PR:
* Uses Go 1.8 executable lookup
* Stores any err message from stats init method
* Allows overriding of Cpu Compute for hosts where it can't be detected
This PR introduces a parallelism limit during garbage collection. This
is used to avoid large resource usage spikes if garbage collecting many
allocations at once.
This PR adds the following metrics to the client:
client.allocations.migrating
client.allocations.blocked
client.allocations.pending
client.allocations.running
client.allocations.terminal
Also adds some missing fields to the API version of the evaluation.
This commit adds Solaris versions of the following functions:
- `linkDir`
- `unlinkDir`
- `createSecretDir`
- `removeSecretDir`
I believe this requires Go 1.8 in order to compile, as the unlink
syscall was previously missing.
Previously, this value was guarded against running on Windows
because it called the `uname` command which is unlikely to
be there.
This change now sets the value from gopsutil, which might
well be an empty string.

Previously with client fingerprinting, sys/exec's Command
function was being used to execute `uname -r` and the return
string processed into the kernel.version node attribute.
This change uses gopsutil/host KernelVersion function
instead. This means we can drop the os/exec, strings and
fmt imports... and not execute an external binary.

This PR fixes two issues:
1) A close of a nil stopCollection channel when restoring and prestart
fails. The failure will cause the killCh to be triggered which will
close collection before it has been initialized.
2) Fixes a deadlock in which the handleWaitCh is never triggered since
it is not initialized when there is an error in prestart and the killCh
is triggered.
Both fixes are by maintaining the loop invariant that the two channels
are valid after there is a handle.
This PR fixes our vet script and fixes all the missed vet changes.
It also fixes pointers being printed in `nomad stop <job>` and `nomad
node-status <node>`.
This PR introduces a coordinator for doing CRUD on a Docker image. It
should fix racy deletion of images. The issue before was images would be
deleted between prestart and start causing an error.
