(maint) Remove stale files from ext/rack

The ext/rack directory had an outdated README file and an ancient manifest.pp
file, and the useful files (config.ru and the example vhost) were buried in a
subdirectory.

This commit removes the old files, moves the good files up a level, and adds a
comment to the vhost pointing to the maintained passenger documentation.
(maint) Update debian packaging to reference new rack support location

As updated in commit 4c9b63f, the sample files for rack passenger deployment
have been moved up a directory. The puppetmaster-passenger package for debian
uses those files, so this commit updates the debian/rules file with their new
location. It also updates the README_DEVELOPER.md, which references the same
files.

(#23126) Allow facter and hiera gem locations to be SSH git URLs

Previously, git urls could only be specified as `git://`. This works
fine for pulling down the puppetlabs facter and hiera repos, but
doesn't allow private forks of those to be pulled down. This is
problematic because the Gemfile is used for setting up our test
environments and the PE versions of facter and hiera are accessed over
SSH.

This commit allows git@ urls in addition to the curreng git: urls.

(#23147) Make the catalog available to the resource during to_catalog

This reverts the logic in the fix for #22943 so that the catalog
is available to a resource during the to_ral conversion.
(#23147) Add alternate fix for #22943.

The original fix for 22943 induced this #23147; this patch
is an alternate fix for #22943 which allows checking the parent
even if it was previously found to be nil (which can happen
if the path is created during to_ral).

(Maint) Make tmp directory more safely

Because the temp directory is not immediately created with the discovered name,
there might be a race condition between tests running on the same machine.
(#7244) Make autosign command treat all non-zero returns the same

Previously the autosign command exit status was checked for three
states: 0, 1, or other.  The latter two would both fail to autosign,
but the other would also raise an exception, so different results
at the client.  We noticed this because the acceptance test
failed on Solaris (which returns 255 for /bin/false, rather than 1).

There doesn't seem to be a compelling reason to treat the non-zero
exit codes differently, so this patch simply removes that distiniction.

(maint) Remove ext/rack/README reference from debian/rules

In a previous commit, files in ext/rack/files were moved up a directory to
ext/rack and some unneeded files were removed. Among the removed files was
README, which was unfortunately still used in the debian/rules file as a
supplemental doc for the puppetmaster-passenger package. The lack of
ext/rack/README caused the rules evaluation to fail, which caused debian
packaging to fail. This commit addresses that by removing the README references
from the debian/rules file.
