Prior to this commit, there was no way to force an override to the PE
version assertion. This commit adds a new parameter that will override
the PE version check and output a warning when enabled. This is useful
in testing new PE versions that are not yet supported by the module.

Improve reliability of downloading PE tarball

The new $permit_unsafe_versions parameter allows the
assert_supported_pe_version() function to not raise on failure, but it
should always return accurate data about whether or not the given
version is or isn't supported.

Add development and testing option to permit installing unsupported PE versions

Adjust message language, add message for moving temp file into target
location on successful download

Rather than expecting that downloaded files will be signed with a known
key, simply use the key from the signature asc file.

The purpose of this validation isn't to validate authenticity. It is
only to validate digest.

Determine validation key from asc signature file

If moving the temporary file into the final location fails, make sure
that error is caught and return values set appropriately.

Catch mv errors when downloading

The PE bash installer script doesn't support re-configuring an existing
agent, which is critical to our use case. Therefore, we should fail if
the agent is already installed, since we cannot guarantee correct
configuration in that scenario.

  * Previously we could spit out logs of what bolt was doing.
    This feature is now natively supported in bolt and there
    is no need for installing inotify and supporting services.

  * Additionally, this adds the old pe installer gpg key

  * Reformats json and yaml files under spec/docker

  * The previously implementation used pdk which ships with an
    older version of bolt.  This allows the user to use the local
    installation of bolt which is the same procedure as using peadm
    directly.

  * This also fixes a few issues around module dependencies and relying
    on the fixtures path.  Users are no longer required to have pdk
    or run bundle commands.  Since this uses pure bolt the entire process
    mimics that of a real installation and usage.

  * Updates install and upgrade scripts to use bolt commands

Fail agent_install if agent is already installed

  * Previously the documentation detailed instructions for
    how to add agents to a docker example cluster.  This
    adds a script to do the dirty work.

Updates docker to use bolt commands

Accidentally closed instead of merging Merging despite broken test @reidmv advised of issue. Will fix the test separately

The gem was updated and the output format changed slightly.

These tests should probably just be removed; they are too exact and
finicky.

Fix failing table output tests
