Initial ci/settings.yml is populated with example parameters (#27)

* initialize settings.yml for boshrelease; assume credhub

* go template attempts to construct ci/settings.yml + display credhub commands

* configure fly -t target using $fly_target

* add initial_settings + credhub helper for cfpush

* credhub helper for docker/base

* assume boshrelease meta.bosh-lite targetting a bosh-lite

* easier to change team before running commands
