[#153091168] Add autopilot plugin to cf-cli docker image

[46bit]

What

We are updating the product page deployment to deploy with a host of www.cloud.service.gov.uk (see alphagov/paas-product-page#44.) For this we need the autopilot cf plugin to be available in cf-cli Docker image being used.

Is there a reason to include and use a second zdd plugin? What is the problem with blue-green-deploy?

[46bit]

@bandesz Sorry, that context was missed. The blue-green-deploy plugin ignores new settings in the app manifest. We have to add new routes to the manifest.json and have them be applied. Autopilot only pays attention to the app manifest, so we've switched to use it here.

[bandesz]

I'm going to approve this now, but just a note that this plugin is not maintained at all and Trade Tariff also reported a strange error: contraband/autopilot#49. We could write the same deployment process with a couple of cf commands.

There's now a version 0.0.4 merged into the official repo: cloudfoundry/cli-plugin-repo#193
