Adding helm chart info to readme and fixing some formatting

[max-rocket-internet]

Now the a helm chart is available in the stable repo, I think we should include it here in the installation instructions. Especially since the YAML files in here are quite out of date.

Alternatively, you can edit node-problem-detector.yaml to fit your environment. Set log volume to your system log directory (used by SystemLogMonitor). For Kubernetes versions older than 1.9, use node-problem-detector-old.yaml.

• Create the DaemonSet with kubectl create -f deployment/node-problem-detector.yaml.
• If needed, you can use a ConfigMap to overwrite the config directory inside the pod.

@max-rocket-internet Thanks for updating this. I suggest adding some comma to make the sentences more readable. Please correct me if there are any un-comfortable changes for your. :) English is not my mother language.

I also suggest we keep the items format for create the daemonset and If needed to make the doc more readable. :)

@max-rocket-internet Just one nit. Others lgtm.

[max-rocket-internet]

Hey @andyxning, I think I've implemented your suggestions, please check 🙂

[andyxning]

@max-rocket-internet Could you please rebase from the master with the latest change for the Installation section.

[max-rocket-internet]

@andyxning I don't really get what you mean. Can you be specific? Edit node-problem-detector.yaml to fit your environment is also repeated twice there. Also there is grammar error environment. and.

[max-rocket-internet]

I think I understand now. Please re-review @andyxning 🙂
