[infrastructure] Prepare an environment to build pazuzu automatically

[elgris]

User story

As a developer I want to have a tool that runs tests and builds pazuzu binary on demand with some build service (Jenkins?).

Acceptance criteria

• Jenkins settings for pazuzu are defined.
• Jenkins runs static analysis tools (go vet, golint) and publishes useful stats
• Jenkins runs tests
