Support to nodes livenessProbe into the Helm Chart (#1897)

In the Helm Chart, there was no ```livenessProbe``` support for option
```chromeNode```, ```firefoxNode```, and ```edgeNode```.

This commit adds these three Helm Chart values:
- ```chromeNode.livenessProbe: {}```
- ```firefoxNode.livenessProbe {}```
- ```edgeNode.livenessProbe: {}```

The bellow properties will end up in the pod livenessProbe for the
respective node pod.

Fixes #1895
