Serve the OPNFV Logo Locally

Because the logo is currently being pulled from an external HTTP site,
the site is being listed as insecure.

Adding the OPNFV logo to static content should fix the warning and keep
the previous error of the logo being moved from happening.

Rename pharos-dashboard and pharos-validator

As subdirectories of the pharos-tools repo, there is little need to keep
the pharos prefix.
