[influxdb] Backup restore readme

By copying /backup/* we are copying all contents, in this case the timestamped backup folder, without the prepending /backup

This is required so that the charts lint & test pipeline succeeds. Furthermore this is the apiVersion for currently supported versions of kubernetes.

* Use github handles instead of real names.

This is required by chart-testing.

* Update e-mail

remove duplicate and updated URL and year

* Convert to markdown.

* Add README

* Use an existing secret for the InfluxDB auth

- Sometimes you need to check in the values.yaml in a repo
and you don't want to expose the secrets. With the existingSecret
option you can use and existing kubernetes secret with the keys
`influxdb-user` and `infuxdb-password` to set the corresponding
environment variables in Kapacitor. The keys are the same as the
ones used in the `influxdb-auth` secret created by the InfluxDB
Helm chart.

* Hardcode probe path.

There is no value in making the path configurable. By hardcoding it to /ping we remove unecessary templating and config complexity.

* Refactor configmap by using implicit default values

Instead of having every default value explicitly described in the values file and put into the corresponding configmap(s), just use defaults and adjust these values as needed. This is beneficial because overtime defaults may change and it is duplicate work to match it in the values file. Furthermore documenting configurable values in the README will be much more feasible. This PR also removes the now defunct admin section of the config.
