Update templates and network policies for rook

[aarnq]

Is your feature request related to a problem? Please describe.
We've faced some issues with the current version of the rook setup.

After upgrading to it we had drop packages going to OSDs which needs to be resolved.
Network policies can also not be configured to be disabled from the config.

Some template fixes from here f07d40c (Only the cluster helmfile values template, the rest is optional.)

And additionally we should tweak the presets to be more sane, for one we should remove resources limits from critical components that we still expect to run on dedicated nodes.

Describe the solution you'd like

Fixes implemented from above.
