(maint) Allow not applying settings catalog on startup

On initialization of a JRuby instance, Puppet will compile and
apply a catalog containing resources for the configured directories
specified in the appropriate settings sections. The goal of this is
to ensure any directories Puppet requires exist. In practice this
should be managed by our packages. Attempting to apply a catalog every
time a JRuby instance is unnecessary, slow, and causes race conditions
when attempting to instantiate JRuby instances in parallel.

Puppet has a setting "settings_catalog" that controls this behavior.
This PR addresses issues that arise when we set "settings_catalog" to
`false`:
 1. In code the process of compiling a settings catalog brings most of
    Puppet's ruby code into scope. When not compiling a settings catalog
    we must actually declare our dependencies.
 2. The $cachedir/yaml/facts directory is not created by packages
    despite being used by default.
