- 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/3592https://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.

**What**
- Bumps the gateway version to 0.10.2 in the default docker-compose file
**Why**

endpoint, this will allow the deployment via compose to leverage the
basic auth

was no credential available.
