Stop avoiding calling systemctl for tgtd on Fedora

The bug that lead to this workaround was fixed and an update is
available for Fedora:
  https://bugzilla.redhat.com/show_bug.cgi?id=797913

Keeping this workaround would be annoying as --skip-redirect doesn't
exist on all rpm-based distributions, and we'd have to remember using it
everywhere we interact with the tgtd service.

Add tar to list of packages to install

It turns out a minimal Fedora installation doesn't have tar by default.
Since we use tar when uploading the default image to glance, we need to
make sure it's installed. And since it might be useful for other very
generic tasks DevStack might do, just always install it (by putting it
in the general list of packages).

update list of files for git to ignore

These files are all created in the course of running
devstack and openstack but should not be tracked
as part of the devstack sources.

Adds new parameter interpolations for tempest config

Tempest recently added a number of new config variables
and this patch merely adds those variables to the
template replacement process in tools/configure_tempest.sh

This needs to go in before this:

https://review.openstack.org/#/c/8738/2

Additionally, this patch sets the build_interval to 3
and the build_timeout to 400. This faster status check
interval should allow Tempest to run a bit quicker in the
Jenkins gate job.

Update info.sh

* Works properly on Fedora 17 now, possibly other RPM-based distros
* Add GetDistro() function taken from logic in stack.sh
* Source functions in tools/info.sh
* Use GetDistro() and get_packages() in tools/info.sh
* Report all installed pips
* Don't sort localrc output as order is important

Allow user to override pip cache location

Building a VM containing devstack is faster if you can save
the cache files for pip in a location that is not deleted
when the VM is rebuilt. This change allows the user to
set the PIP_DOWNLOAD_CACHE in their localrc file to point
to any directory writable by root, including a directory
mounted from the host containing the VM.

Don't setup swift3 if it's not being used.

"setup_develop" was still being called for swift3, even if it's
not in enabled services.  This wraps that call in an
"is_service_enbled" conditional so that stack.sh doesn't attempt
to set it up if it's not enabled.

- Fixes bug 1021150.
