Omit Namespace Options

[judexzhu]

Hi, I've seen we have the options to select which namespaces like to watch in the helm chart.

# namespace to watch, leave it empty for watching all.
namespaceToWatch: ""

This is great, but I think most of my scenarios is I only have a few namespaces I don't like to watch but I like to watch the rest of the others, including the newly created one.

for example:

I have a namespace for stolon, which keeps updating it's pods events every a few seconds, and this annoying me a lot, I have to set the pod watch to "false"

sorintlab/stolon#463

in this case, I'd like to omit the stolon namespace but watch the others.

Thanks
