Generate setup job yaml from helm template

[rvmiller89]

Description

Updates the CI build.sh script to generate a new template yaml file setup-sumologic.yaml.tmpl that contains all of the setup Helm templates needed to run a job on Kubernetes to setup the Sumo Logic collector and HTTP sources, namespace and secret.

In order to use the job yaml, you must first create the sumologic namespace:

kubectl create namespace sumologic

And then update these parameters in the yaml template:

1. $NAMESPACE
2. $SUMOLOGIC_ACCESSID
3. $SUMOLOGIC_ACCESSKEY
4. $COLLECTOR_NAME
5. $CLUSTER_NAME

This can be added to our README in a future PR. One thing I did notice is it leaves the setup pod as 0/1 Completed but I think that's okay to leave:

k8s $ k get pods
NAME                               READY   STATUS      RESTARTS   AGE
collection-sumologic-setup-bj65t   0/1     Completed   0          40m

Testing performed

• ci/build.sh
• Redeploy fluentd and fluentd-events pods
• Confirm events, logs, and metrics are coming in
