release beaker 1.2.0
Install agents using the frictionless agent install

This change adds logic for installing using the new curlbash style of
agent install. In order to support testing both the old and new styles
of install, we add a new agent role of "frictionless", which indicates
that the node should be installed in the new style. This simply causes
it not to download the PE tarball or generate answer files, and to curl
and run a script from the master (based on the platform tag).
Validate that we don't allow frictionless master, etc

Frictionless install is only supported for agent-only installs, so we
check that any frictionless node doesn't have any non-agent roles
specified.
(QE-613) Add `:catch_changes` to check for manifest resource changes

Many times when testing modules we apply puppet code twice in a row and
verify that the second run does not produce any resource changes to
verify that the resources are idempotent. The `:catch_changes` option
can be used to monitor for this result.

(QE-588) vcloud_pooled: undefined method `request_uri'

- ensure that a scheme is defined for the vcloud pooling api uri
- if no scheme is defined the uri returned is a simple uri object that
  does not support the 'request_uri' method

expanded log level support

- support the following levels:
  5 debug

  1 warn
- each level reports itself plus the levels under it
- added 'info' level that reports in BLUE
- 'debug' level adds full stack traces
- todo: would like to review our current logging messages and see
        what needs to be assigned a new level
