Set Tempest storage protocol and vendor w/o setting driver

Set TEMPEST_STORAGE_PROTOCOL and TEMPEST_VOLUME_VENDOR if
they are changed from their defaults, or if
TEMPEST_VOLUME_DRIVER is changed.

This maintains the current behavior of setting these options if
TEMPEST_VOLUME_DRIVER is set to something other than "default".

Update multiple backend configuration in tempest script

Currently when we configure the tempest with multiple LVM
backends the backend names are created as LVM_iSCSI and
LVM_iSCSI_2 which fails since the backends created by cinder
are lvmdriver-1 and lvmdriver-2.

This patch updates the backend names. Added support for
CINDER_ENABLED_BACKENDS and added todo to remove
CINDER_MULTI_LVM_BACKEND once its formally removed

Make screen_service() useful for more than services

screen_service() can currently only be used to launch things that
pass the 'is_service_enabled' check, even though its calling functions
will have already done this.  This removes such check, renames it
to screen_process() and updates its usage elsewhere.

Reference git.o.o DevStack repo rather than GitHub

In docs, use git.o.o URLs rather than GitHub URLs for the DevStack repo,
and don't mention GitHub when git.o.o is more appropriate.
Also, replaced GitHub logo with Git logo in quickstart.png.

Remove internal bash8

Convert all HTML doc to RST

The motivation for this conversion is to have DevStack's docs be
generated using a more familair workflow for OpenStack projects, using
Sphinx.

Changing from raw HTML to RST will also make it easier to contribute
more documentation, as well as making edits less of a hassle.

The majority of the work was done by using Pandoc to convert from HTML
to RST, with minor edits to the output to remove errors in Sphinx.

Use service tenant id for Ironic agent swift auth

Config of ironic conductor currently references a non-existent variable.
This corrects it by obtaining and using the correct tenant id.

Fix an issue with setting tempest volume vendor_name with spaces

If the volume vendor has spaces in it, for example “Open Source”, we
need to have quotes around the uses of the variables or the behavior
will not be as expected.

Move to download.fedoraproject.org

download.fedoraproject.org is the mirror system, while
dl.fedoraproject.org is just one system. We have seen performance issues
with dl.fedoraproject.org and using download.fedoraproject.org was a
recommended as a solution by the folks at #fedora-admin.

Local testing on a rackspace server with dl.fedoraproject.org got about
70K/s while download.fedoraproject.org got over 1M/s

Move over to https as well.
