... it were executed on the command line
- simply remove the option hash from the debug line, it isn't
  appropriate there.

(QENG-912) Beaker 1.14 breaks PE Puppet Acceptance

- was too conservative in removing non utf-8 compliant characters -
  ended up removing compliant characters along with undef/invalid
  character codes
- tested locally and it preserved messages like:
/etc/puppet/modules
├── jimmy-appleseed (v1.1.0)
├── jimmy-crakorn (v0.4.0)
└── jimmy-thelock (v1.0.0)
- correctly removed actual undef/invalid characters so that string
  methods can be run (ie, split, gsub)

(QENG-923) Ensure @codename is set if platform string has codename

Beaker 1.14.0 and up has a change to Beaker::Platform which ensures that
@version and @codename is set if the platform string contains the
version number, and that @version is set if platform string contains the
codename, but it fails to set the @codename in this later case.

Puppet currently has debian/ubuntu configs checked (used in ci) which
use platform strings of the form debian-wheezy-x86_64. We could change
these, but it looks like the intention of the Beaker::Platform object is
to provide @version and @codename (where codenames are used).

This patch ensures that @codename is set along with @version in these
cases.

(QENG-927) Beaker does not honor --fail-mode always fails fast

- bug comes from regex comparison with a symbol not being coerced to a

(QENG-188) Allow foss runs to use service scripts

Prior to this commit, any run of beaker with a non-pe master that
attempted to stand up a master with a particular configuration in order
to test against it using the with_puppet_running_on() helper would
always stand up a webrick master by executing `puppet master <args>` and
then later stop it with `kill`.

The platform team needs to be able to run acceptance suites in which the
puppetmaster is started/stopped using package provided init scripts, or
by restarting apache if a passenger puppetmaster package is installed.

This PR makes a few additions to OptionsHash, Host and the DSL::Helpers
to allow us to distinguish foss hosts which were spun up from source
from those which were installed from packages.  And if we are working
with packages, whether we will be attempting to restart a running
service or stop/start using service scripts.
