* Update docs for bolt 3.x and new auto module dependency download
  * Updated version of supported bolt
  * Detailed more usage of staging directory

Implement changes to Plan[peadm::action::install] to take advantage of
expiremental parallelize() function to facilitate code clean-up and
determine if it can be used to improve performance of PE installation
process.

Make use of parallelize() function

Updated docs to reflect bolt 3.5 usage

Previously, the pe_install task would ignore any erroneous exit codes
emitted by the pe installer. This caused user confusion because actual
failures to install resulted in strange errors later in the plan. This
commit improves the user experience by ensuring some basic smoke tests
pass, or else actually failing at this step.

It can be done at the same time other agents are installing

When signing CSRs, it is common that the CSR will have been submitted
just prior. Previously, plans which did both would have to pause after
submitting the CSR to ensure there was time for the server to have fully
processed it before running the sign task, in order to avoid any chance
of ready-to-sign timing problems.

This commit makes the sign_csr task itself attempt to sign up to six
times, waiting one second between attempts, in order to avoid needing to
do that in the plan.

This is currently in testing

This allows Target objects to indicate the certname that should be used
for them by setting a var. Using a var avoids needing to construct new
Target objects when/if the target object doesn't have a name, but the
uri isn't a valid certname. In that circumstance, just set_var(certname,
...) on the target.

This better reflects that the certname can now be different from the
target name by way of a certname var.

In the event a Target or Array[Target] is passed for $primary_host, the
default for compiler_pool_address needs to be made compatible.

Remove this constraint when the referenced bug is resolved.

Projects do not support functions, so having this file around is
problematic because it prevents `bolt plan run peadm::*` plans from
executing correctly when run from inside the module folder.

The project.yaml file was originally added to make testing/using the
module easier. However, since then, this has become an option:

    bolt project init my_org --modules puppetlabs-peadm

Given an easy way of downloading and using the module, removal of the
bolt-project.yaml file to fix other problems is the thing to do.

This fixture contains plans used in acceptance testing of peadm, such as
provisioning test systems, and installing PE on them.

Cloud CI VMs expire in two hours, so there's no point letting the
install step run longer than that.
