Foreman » Installer

Foreman will soon get ability to log to JSON format natively.

Candlepin supports ability to configure logging pattern to arbitrary string: http://www.candlepinproject.org/docs/candlepin/logging.html

Pulp team was asked to add the same configuration option: https://pulp.plan.io/issues/3372

After this is added to pulp, we need an installer option in katello scenario called for example log_format. When set to json instead of plain, installer will configure foreman components (rails, proxy) to log to JSON and for candlepin/pulp it will create a pseudo-JSON logging pattern that will be easily parseable for 3rd parties:

{ "message": "%m", "request": "%X{requestUuid}", "org": "%X{org}", "correlation": "%X{csid}" }%n

Similarly for Pulp (it will likely have different replacement keys).
