Add base_package_type

Currently in all the Dockerfile.j2 files, we are doing base distro if
conditions for package names when installing via a binary.  Rather than
duplicating these base_distro in [<distros>], let's provide a single
value for determining the binary installation method. This change adds a
base_package_type which we can use to lookup if 'rpm' or if 'deb' rather
than relying on specific distro names.

+    Add `base_package_type` which can be used in Dockerfile.j2 files instead
+    of checking based on distro names. This will default to "rpm" for RHEL
