Concourse deploy pipeline

[hsiliev]

We need to provide a simplified deployment pipeline that demonstrates how we can deploy all Abacus components.

Old pipeline (deleted with 3539bc1e27707c61d74b8263775f012d6793c307) was:

• untested
• using service instances we now no longer support
• complex
• using own tooling and concepts instead of cf CLI substitution variables and manifests directly

[cf-gitbot]

We have created an issue in Pivotal Tracker to manage this:

https://www.pivotaltracker.com/story/show/160920191

The labels on this github issue will be updated when the story is started.

All Abacus apps now have manifests that support substitution variables as a prerequisite for the new pipeline.
