Add the option to set up a certificate whitelist file and configure it
in PuppetDB so that only specific hosts (i.e. the Puppet master(s)) have
access.
Currently the module only allows PuppetDB to be configured in a
agent/master setup configuration, by configuring the master section of
the puppet.conf and applying on the routes for such a configuration.
This commit allows one to use this module to configure the main section of
the puppet.conf and applying the proper routes so the module can configure
nodes to use PuppetDB in a masterless setup.
Doc about puppet.conf configure in masterless way available here
https://docs.puppetlabs.com/puppetdb/2.2/connect_puppet_apply.html#manage-puppetconf
The test manifests for single-node (everything installed on
the master machine) now work properly. You have to
edit your puppet.conf by hand to turn on storeconfigs and
point it at puppetdb, but other than that, this successfully
handles everything that you need for either an hsql or
postgres setup.
