The generated version of the protobuf did not match the `.proto` file.
This caused issues when a new protobuf change was added

It is unnecessary to create a namespace just to test that it exists.
Roles that don't have post namespace will error out even if the namespace exists
and it is possible to install the package anyway. This patch Gets a namespace and

It allows globals to be nested maps.

Adds `--tiller-namespace` flag and `TILLER_NAMESPACE` envvar
to use tiller in an alternate namespace.
