When uploading from standard input, swiftclient should turn the upload
into an SLO in the case of large objects. This patch picks the
threshold as 10MB (and uses that as the default segment size). The
consumers can also supply the --segment-size option to alter that
threshold and the SLO segment size. The patch does buffer one segment
in memory (which is why 10MB default was chosen).

(test is updated)

> For many projects, tox_install.sh is not needed at all

Let's see if that holds for python-swiftclient!

This reverts commit f2f278fcbec3ad52a1726bb5a3f775d13bcc99dc.

I noticed a disturbing lack of quote-wrapping in change
I7cb4b44952713752435e1faf0f63bf0d37e7dda6 but as I poked at it, I
realized that trouble runs rampant.

This seems to clean it all up, though I haven't tested *every*
environment we define.

The updates to the sphinx docs jobs in support of the updates to
the PTI wound up exposing an unintended interface. There are two flavors
of the tox_install.sh file out there, and we basically need to collapse
them into one flavor.

Update the tox_install.sh script to match the
constraints-as-first-argument form.

Release notes are version independent, so remove version/release
values. We've found that projects now require the service package
to be installed in order to build release notes, and this is entirely
due to the current convention of pulling in the version information.

Release notes should not need installation in order to build, so this
unnecessary version setting needs to be removed.

This is needed for new release notes publishing, see
I56909152975f731a9d2c21b2825b972195e48ee8 and the discussion starting

Also, don't try to do any pypy stuff on Fedora -- apparently that's only
available from the Everything repo instead of the stripped-down Server
one the gate images use? I only wanted Fedora for py36 testing, anyway.
