This reverts commit 15c48668.

Use "root", apparently travis user is unable to grant users? https://travis-ci.org/aegir-project/provision/jobs/299909023#L726

- Convert Context->type to Context::TYPE because it is not allowed to change and we can access it statically.
- Create static method findAvailableServices() so we can call it in InputDefinition.
