Configure host type as AIO

Previously, when running with beaker 5 and latest beaker-puppet, tests failed
with:

    cannot add defaults of type pe for host redhat7-64-1 (add_pe_defaults_on not present)

The error came from beaker-puppet when it tried to configure the host as a PE
agent[1].

The root cause is beaker defaults its options to `pe`[2]. When `beaker-puppet`
calls the `configure_type_defaults_on` method, it calls the appropriate
`add_<type>_defaults_on` method. This works when using beaker 4 as `beaker-pe`
is pulled in as a dependency and its `add_pe_defaults_on` method[3] is included
into the tests.

However, when running with beaker5, beaker-pe is not loaded, so the method is
undefined. It appears beaker-puppet_install_helper is responsible for the
whether beaker-pe is loaded or not, but only when using
beaker-puppet_install_helper 0.9.4.

Since these tests don't actually depend on PE, drop beaker-pe, require
'beaker-puppet' directly (so the install_from_build_data_url method exists) and
configure the host type directly.
