Enable bbCommonValues for packages by default
The Big Bang packages key supports passing in bb-common compatible values to a package via an additional flag `bbCommonValues`.
An example looks like
```yaml
packages:
podinfo:
namespace:
name: podinfo
helmRelease:
namespace: "bigbang"
enabled: true
sourceType: "git"
git:
repo: https://repo1.dso.mil/big-bang/product/maintained/podinfo.git
bbCommonValues: true
```
Given that we view bb-common integrated packages to be most common pathway for helm charts deployed with the packages: key, we should set `bbCommonValues` to true by default.
