(PE-27608) Master branch PEZ logic

[cthorn42]

In order for PEZ builds to be located correctly we need to add in some
logic. This PR adds to the Master branch logic by looking at the tarball
string and seeing if it is a PEZ tarball. If so point the pe_dir to the
feature directory, where the PEZ tarballs are put.

Oh also this pulls out the master PE version, which will change for PE releases. We'll need to bump that as time goes on.

This is the non-pez example of things working:

pe_version=2019.4.0-rc2-40-g1043f13 bundle exec beaker-hostgenerator redhat7-64mcd
---
HOSTS:
  redhat7-64-1:
    pe_dir: https://artifactory.delivery.puppetlabs.net/artifactory/generic_enterprise__local/master/ci-ready
    pe_ver: 2019.4.0-rc2-40-g1043f13
    pe_upgrade_dir:
    pe_upgrade_ver:
    platform: el-7-x86_64
    packaging_platform: el-7-x86_64
