Michael Schurter 195b8127fb health_hook: fix panic and add tests 
Still more testing to do, but I want to get this panic fixed ASAP.

Michael Schurter 64efc3d301 Emit events before long operations 
Append when there's nothing blocking between appending and sending an
update to the server.

Michael Schurter a7b427718c tr: refactor EmitEvents into Emit+Append 
* UpdateState: set state, append event, persist, update servers
* EmitEvent: append event, persist, update servers
* AppendEvent: append event, persist

AppendEvent may not even have to persist, but for the sake of
correctness I'm going with that for now.

Michael Schurter e42154fc46 implement stopping, destroying, and disk migration 
* Stopping an alloc is implemented via Updates but update hooks are
  *not* run.
* Destroying an alloc is a best effort cleanup.
* AllocRunner destroy hooks implemented.
* Disk migration and blocking on a previous allocation exiting moved to
  its own package to avoid cycles. Now only depends on alloc broadcaster
  instead of also using a waitch.
* AllocBroadcaster now only drops stale allocations and always keeps the
  latest version.
* Made AllocDir safe for concurrent use

Lots of internal contexts that are currently unused. Unsure if they
should be used or removed.

Michael Schurter 637ef264ae Copy TR.Config vals to TR 
I think I like this pattern better as some Config vals are mutable
(Alloc) and some aren't and some are used to derive other values and
never used directly.

Promoting them onto the TR struct is a little more work but is hopefully
more clear as to how each value is used.

Michael Schurter 0f7dcfdc9a example redis job "runs" on arv2! see below 
Tons left to do and lots of churn:
1. No state saving
2. No shutdown or gc
3. Removed AR factory *for now*
4. Made all "Config" structs local to the package they configure
5. Added allocID to GC to avoid a lookup

Really hating how many things use *structs.Allocation. It's not bad
without state saving, but if AllocRunner starts updating its copy things
get racy fast.

fix: increase log rotator line scan limit 
In case where gelf/json logging is used, its fairly easy to exceed the 16k limit, resulting in json output being cut up into multiple strings

the result is invalid json lines which can create all kind of badness in the logging server

This fixes https://github.com/hashicorp/nomad/issues/4699

Michael Schurter 6def5bc4f9 client: set host name when migrating over tls 
Not setting the host name led the Go HTTP client to expect a certificate
with a DNS-resolvable name. Since Nomad uses `${role}.${region}.nomad`
names ephemeral dir migrations were broken when TLS was enabled.

Added an e2e test to ensure this doesn't break again as it's very
difficult to test and the TLS configuration is very easy to get wrong.

Michael Schurter a1d4f77ce0 rkt: skip retrieving network information when net=none 
Even when net=none we would attempt to retrieve network information from
rkt which would spew useless log lines such as:

```
testlog.go:30: 20:37:31.409209 [DEBUG] driver.rkt: failed getting network info for pod UUID 8303cfe6-0c10-4288-84f5-cb79ad6dbf1c attempt 2: no networks found. Sleeping for 970ms
```

It would also delay tests for ~60s during the network information retry
period.

So skip this when net=none. It's unlikely anyone actually uses net=none
outside of tests, so I doubt anyone will notice this change.

Add 'nomad.advertise.address' to client meta via NomadFingerPrint 
This change removes the addition of the advertise address to the
exported task env vars and instead moves this work into the
NomadFingerprint.Fingerprint which adds this value to the client
attrs. This can then be used within a Nomad job like
${attr.nomad.advertise.address}.

This commit changes the force closing of the stdout/stderr file
descriptor from closing immediately to being closed after a grace
period. This allows the created process to close its own file and allows
copying of the data.

Justen Walker 60f7f1aa08 driver/docker: pull image with digest 
GH #4290

Add digest support to the docker driver image config. This commit
factors out some common code to print the repo:tag (dockerImageRef) for
events/logs as well as parsing the image to retreive the repo,tag
(parseDockerImage) so that the results are consistent/sane for both
repo:tag and repo@sha256:... references.

When pulling an image with a digest, the tag is blank and the repo
contains the digest. See:
https://github.com/fsouza/go-dockerclient/blob/master/image_test.go#L471

We attempt to avoid splitting a log line between two files by detecting
if we are near the file size limit and scanning for new lines and only
flushing those.

consul: remove services with/without canary tags 
Guard against Canary being set to false at the same time as an
allocation is being stopped: this could cause RemoveTask to be called
with the wrong Canary value and leaking a service.

Deleting both Canary values is the safest route.

consul: support canary tags for services 
Also refactor Consul ServiceClient to take a struct instead of a massive
set of arguments. Meant updating a lot of code but it should be far
easier to extend in the future as you will only need to update a single
struct instead of every single call site.

Adds an e2e test for canary tags.

client/driver: remove pull timeout due to race condition that can lead to unexpected timeouts 
If two jobs are pulling the same image simultaneously, which ever starts the pull first will set the pull timeout.
This can lead to a poor UX where the first job requested a short timeout while the second job requested a longer timeout
causing the pull to potentially timeout much sooner than expected by the second job.

didn't break the reference from the sent frame to the StreamFramer's
data slice.

I could find no evidence that *not* calling Reset() caused bugs, but
might as well do what the docs say?
