Previous Spec was flawed as it showed that the response model was
```
[
  {
    "name": "aws-key",
    "value": "changeme"
  }
]
```
Changed the model to match what is returned

**What**
- Removes the `alert` label in the scale-up alert
- Updates the annotaitons to use the `function_name` label instead of
the `instance` label that was removed.
- Per prometheus/prometheus#4836 and the related mailing list discussion
https://groups.google.com/d/msg/prometheus-users/7Ul6ngc7Ogs/j_YDszV5BwAJ


the alert value should not be included in the alert labels otherwise
each calculation of the alert is treated like a new alert and then the
use of `for 5s` will not behave as expected.
- Ports the resoltuion openfaas/faas-netes#372

- max_conns / idle / per host are now read from env-vars and have
defaults set to 1024 for both values
- logging / metrics are collected in the client transaction
rather than via defer (this may impact throughput)
- function cache moved to use RWMutex to try to improve latency
around locking when updating cache
- logging message added to show latency in running GetReplicas
because this was observed to increase in a linear fashion under
high concurrency
- changes tested against 3-node bare-metal 1.13 K8s cluster
with kubeadm

- due to what appears to be a frequent issue with the Go HTTP
client some tweaks were needed to the HTTP client used for
reverse proxying to prevent CoreDNS from rejecting connections.

The following PRs / commits implement similar changes in
Prometheus and Minio.

https://github.com/prometheus/prometheus/pull/3592
https://github.com/minio/minio/pull/5860

Under a 3-node (1-master) kubeadm cluster running on bare
metal with Ubuntu 18.04 I was able to send 100k requests
with 1000 being concurrent with no errors being returned
by hey.

```
hey -n 100000 -c 1000 -m=POST -d="hi" \
  http://192.168.0.26:31112/function/go-echo


```

The go-echo function is based upon the golang-http
template in the function store using the of-watchdog.
