Install acme.sh LE client from github.com/Neilpang/acme.sh.

This just installs the script/client only. You still need to do any certificate requests manually, as well as configure your web server.

Needs the following parameters:

• $acme_repo_path - The full path to clone the acme.sh git repository in order to install from.
  (default: '/opt/acme_repo')

• $acme_home - The full path to install the acme.sh script into (overriding $HOME/.acme.sh).
  (default: '/opt/acme')

• $acme_certhome - A customized dir to save the certs you issue.
  (default: $acme_home)

• $acme_accountemail - Specify the email address to be used in Letsencrypt API communications. This email address will later receive certificate expiry warnings.
  (default: undef)

• $acme_version - The version/release of the acme git repository to clone.
  (default: 'master')

• $manage_dependencies - Boolean to specify whether or not to install the required package dependencies.
  (default: false)

Only explicitly tested on RHEL/CentOS 6 and Debian 7.

This module requires puppetlabs/vcsrepo.
