(QENG-846) Add timestamp to options hash.

This makes the timestamp available globally during Beaker runs so it can be used
to add files to the specific run's log directory without being confused by other
simultaneous runs of Beaker due to the use of log/latest symlink.

(QE-683) install_package_version

This commit adds 'install_package_version' method to the DSL helper utils and an
associated method that given package name as well as optional version string
that will be used to construct a package name that includes a specific version
string for installation on the SUT.

This currently only supports apt and yum based package managers, as I am no
familiar enough with other platforms. For non apt or yum based platforms, an
exception will be raised.

(QE-725) Implements install_from_ezbake.

Adds a new module, Beaker::DSL::EZbake to extend the Beaker DSL with
functionality that should be useful across multiple JVM based projects,
particularly those that use TrapperKeeper and are packaged using ezbake.

(QE-725) Update install_from_ezbake.

Updates to fix bugs in conditionally_clone and install_from_ezbake.

Don't want to add user to system from install_from_ezbake, that should be done
at a higher level or from within a preinst step if absolutely necessary. Also
shouldn't be making any puppet calls using Beaker before the Puppet master is
run for the first time using init scripts since this will lead to
/var/lib/puppet directories being owned by root. Bad.

(QE-683) Add package_version option to install_package.

Makes more sense to make this optional behavior in `install_package` than to
implement new method.

(QE-725) Improve install_from_ezbake

Need to be able to pass in arbitrary key-value pairs to add to environment in
which `make` is called on the given host in install_from_ezbake. If the hash is
empty, then don't prepend the `env` call to make.

(QENG-715) Add `install_dev_repo` to Beaker DSL

This is a "push" style method of installing a dev repo from
builds.puppetlabs.lan by first downloading to a directory on the local machine
then pushing to the appropriate configuration directory on the remote machine.
