Add integration tests

Browse Source 
These tests are small Spring Cloud Kubernetes application that are
deployed inside a Kubernetes cluster launched with microk8s.
The deployment of the applications is done with the Fabric8 Maven Plugin

# Purpose
Demonstrate how integration tests can be run against a local cluster setup with [microk8s](https://microk8s.io/)
The Kubernetes resources necessary to get the test application
onto the cluster are created using the [Fabric8 Maven Plugin](https://maven.fabric8.io/)
# Instructions
## Install microk8s
```bash
sudo snap install microk8s --classic --channel=1.11/stable
sleep 10
microk8s.enable dns registry
```
Ensure everything is running by inspecting the output of:
```bash
microk8s.kubectl get all --all-namespaces
```
It should look something like:
```
NAMESPACE NAME READY STATUS RESTARTS AGE
container-registry pod/registry-6bc95dfd76-274lc 1/1 Running 0 40s
kube-system pod/hostpath-provisioner-9979c7f64-f96tw 1/1 Running 0 41s
kube-system pod/kube-dns-864b8bdc77-68kmn 2/3 Running 0 41s
NAMESPACE NAME TYPE CLUSTER-IP EXTERNAL-IP PORT(S) AGE
container-registry service/registry NodePort 10.152.183.175 <none> 5000:32000/TCP 50s
default service/kubernetes ClusterIP 10.152.183.1 <none> 443/TCP 1m
kube-system service/kube-dns ClusterIP 10.152.183.10 <none> 53/UDP,53/TCP 56s
NAMESPACE NAME DESIRED CURRENT UP-TO-DATE AVAILABLE AGE
container-registry deployment.apps/registry 1 1 1 1 50s
kube-system deployment.apps/hostpath-provisioner 1 1 1 1 51s
kube-system deployment.apps/kube-dns 1 1 1 0 56s
NAMESPACE NAME DESIRED CURRENT READY AGE
container-registry replicaset.apps/registry-6bc95dfd76 1 1 1 41s
kube-system replicaset.apps/hostpath-provisioner-9979c7f64 1 1 1 41s
kube-system replicaset.apps/kube-dns-864b8bdc77 1 1 0 41s
```
## Setup environment for FMP to work
One premise for the Fabric8 Maven Plugin to work is that is can read the proper Kubernetes Config file.
We export the corresponding config file for the cluster microk8s sets up to temp file which will
be used later
```bash
microk8s.kubectl config view --raw > /tmp/kubeconfig
```
## Deploy application
**The following commands assume that they are executed inside the maven module of each specific test**
Since FMP is based on the Fabric8 Kubernetes Client, we can leverage the `KUBECONFIG` environment variable
to make FMP aware of the Kubernetes Config file we created above
```bash
export KUBECONFIG=/tmp/kubeconfig
../../mvnw clean package fabric8:build fabric8:push fabric8:deploy -Pfmp
```
Make sure the application was deployed be executing:
```bash
microk8s.kubectl get pod -l app=sb-fmp-microk8s
```
It should look something like:
```
NAME READY STATUS RESTARTS AGE
simple-core-5fbb7646dc-66t7b 1/1 Running 0 57s
```
The integration tests can be run against the service which is deployed inside the cluster by executing:
```bash
../../mvnw verify -Pfmp,it -Dfabric8.skip
```
This integration tests runs locally (making it easily debuggable), and interacts with the deployed service
using the exposed port.
By leveraging [Aquillian Cube Kubernetes](http://arquillian.org/arquillian-cube/#_kubernetes), it's able to setup and teardown resources needed for each test
To undeploy the application from the cluster simply execute:
```bash
../../mvnw fabric8:undeploy -Pfmp
```
## Run all tests
By executing
```bash
deploy_test_undeploy_all.sh
```
each one of the test applications will be deployed to the cluster and the integration tests will be executed
