Anchore Engine security scan support

[bonifaido]

Summary

This PR adds support for Anchore Engine based security scanning.

Also, it improves the stabality of security scans, so crashed scans can be restarted easily, and nil returned by scanners means in-progress.

Docker-compose based dev environment improvements:

• support for non-linux based Docker for Mac environment
• the registry was changed to use TLS (clair supports http and https as well, but anchore supports only https)

I would also add some parts to the development docs, how to test the Anchore based stuff.

Also I plan to add an Anchore feed check, so if /v1/system/feeds returns an empty result (see below), we don't return any results (just wait in a loop).

        ],
        "last_full_sync": null,
        "name": "vulnerabilities",
        "updated_at": null
    }
]

Update: just added this ☝️

NOTE: The registry has to be added to Anchore with the follwing cURL/Httpie command:

http --auth admin:foobar anchore:8228/v1/registries registry_user=admin registry=registry:5000 registry_pass=adminpass registry_verify:=false

@mssola is there anything we can do in this PR?

I think it's a great addition to the project, competing projects (like Harbor) already added support for it.

[SuperSandro2000]

I myself consider this project dead or without a maintainer.

[bonifaido]

Yeah possibly, at least it looks like that.
