# @api private
#
# @summary Perform initial installation of Puppet Enterprise Extra Large
#
# @param r10k_remote
#   The clone URL of the controlrepo to use. This just uses the basic config
#   from the documentaion https://puppet.com/docs/pe/2019.0/code_mgr_config.html
#
# @param r10k_private_key_file
#   The private key to use for r10k. If this is a local file it will be copied
#   over to the primary at /etc/puppetlabs/puppetserver/ssh/id-control_repo.rsa
#   If the file does not exist the value will simply be supplied to the primary
#
# @param license_key_file
#   The license key to use with Puppet Enterprise.  If this is a local file it
#   will be copied over to the MoM at /etc/puppetlabs/license.key
#   If the file does not exist the value will simply be supplied to the primaries
#
# @param pe_conf_data
#   Config data to plane into pe.conf when generated on all hosts, this can be
#   used for tuning data etc.
#
# @param pe_installer_source
#   The URL to download the Puppet Enterprise installer media from. If not
#   specified, PEAdm will attempt to download PE installation media from its
#   standard public source. When specified, PEAdm will download directly from the
#   URL given.
