Fixes the following error

Error: /Stage[main]/Puppetdb::Server/Cron[puppetdb-dlo-cleanup]: Could not evaluate: Cannot write the puppetdb user's crontab: The user does not exist

PuppetDB runs as the puppetdb user.  This user must have read access to
the various configuration files but does not need write access to them.

This ensure the service configuration cannot be unexpectedly changed by
PuppetDB itself if some vulnerability allow random code execution,
limiting the possibilities of exploitation and pivoting if such a
vulnerability is found.

The code changes add a new Facter fact called `puppetdb_version` that retrieves the version of PuppetDB installed on the system. It uses the `puppetdb --version` command to fetch the version and returns it as a fact value.

Add a `puppetdb_version` fact with PuppetDB version
