cmd/ansible-operator,cmd/helm-operator: embed code in main.go

[joelanford]

Description of the change:

• Remove ansible.Run() and helm.Run() functions and move code to refactored ansible and helm main.go files
• Remove shared WatchFlags and duplicate those flags in both the ansible and helm operator flag structs.

Motivation for the change:

• Ansible and Helm operator code should be more self-contained in preparation for 1.0 release.

At first I didn't like this idea, I prefer a small main.go with another layer to do most of the work, but this looks okay to me. This might impact @VenkatRamaraju PR #3374
