CPI job name is incompatible with multi-CPI

[bgandon]

The job name is currently shadow-cpi in this Bosh release, whereas Bosh expects it to be shadow_cpi as per the multi-CPI docs: “Director will add _cpi suffix to the end of the type when calling the CPI binary”.

A possible workaround is to create a symbolic link for providing the shadow_cpi job as an alias of shadow-cpi with such YAML patch:

- path: /instance_groups/name=bosh/jobs/name=pre-start-script?
  type: replace
  value:
    name: pre-start-script
    release: os-conf
    properties:
      script: |
        #!/usr/bin/env bash
        set -ex
        cd /var/vcap/jobs
        ln -sfn shadow-cpi shadow_cpi

And this requires the os-conf release in the deployment manifest. It that may already be there, but can also be added with such YAML patch:

- path: /releases/name=os-conf?
  type: replace
  value:
    name: os-conf
    version: ((os_conf_version))
    url: https://bosh.io/d/github.com/cloudfoundry/os-conf-release?v=((os_conf_version))
    sha1: ((os_conf_sha1))
