Updated tablegen.py to process the configuration options from the values.yaml
files under /istio/install/kubernetes/heml/subcharts directory and the
remaining configuration options like global, istiocoredns, istio_cni from
values.yaml under /istio/install/kubernetes/helm/istio directory.
* Fixes: #2136
This is a first take at a table-creating tablegen that categorizes
the output of tablegen.py. Still needed is the actual text that
goes in the description field.
* Address review comments
As well as their default value. I will work more on the python
generation tool this evening after dinner and push an update, but
it makes alot of sense to just merge this as is assuming it renders
properly.
