enable overriding mod-level parameters for apache::mod::passenger

apache::mod::passenger didn't accept/pass (optional) mod parameters
through to apache::mod, so only auto-generated module parameters were
used.  Without this option apache::mod::passenger could not be used in
conjunction with passenger modules beyond those generated by OS package
system (in particular, modules compiled via
passenger-install-apache2-module, which use differing paths).  This
commit enables passing in all parameters used with "apache::mod",
documented in the passenger README

includes basic spec/acceptance tests; verifying a default installation
as well as passing in module loading parameters.

new tests revealed undocumented Redhat dependencies on a passenger-
specific repository as well as the EPEL repository; as a first step
these dependencies are being manually resolved during setup for the
acceptance testing suite.

Modified default RedHat passenger parameters for cleaned-up
installation (prior parameters worked with Apache, but broke
passenger-* utilities, incl. passenger-status & passenger-root).

Updated spec/class tests to verify mod-level parameters; also,
updated RedHat tests to accomodate updated default parameters.

Added spec/acceptance tests for passenger, verifying default
installations for RedHat and Debian systems. RedHat installation test
installs (required) EPEL and http://passenger.stealthymonkeys.com
package repositories.

fix inverted ssl compression

Apache 2.4 defaults SSLCompression Off. The ssl module provides a
parameter for ssl_compression which defaults false. If it is set
to true, the template actually would add another SSLCompression Off
stanza (not the expected SSLCompression On).
allow global setting of SSL cipher

ssl_cipher is setable per vhost already, this makes it an option
that can be sent once per the entire configuration instead of at
each vhost.
