Add GIT_TIMEOUT variable to watch git operations

During my CI testing of each devstack change I can often see git get
itself stuck and hang indefinitely.  I'm not sure if it's transient
network issues, or issues at the remote end (seen with both github.com
and git.openstack.org) but it hits fairly frequently.  Retrying the
command usually gets it going again.  Searching for "git hanging" and
similar shows its not entirely uncommon...

This adds a watchdog timeout for remote git operations based on a new
environment variable GIT_TIMEOUT.  It will retry 3 times before giving
up.  The wrapper is applied to the main remote git calls.

Add end-of-file checks to bash8

Add two end-of-file checks to bash8.  Firstly, alert if heredoc hasn't
finished.  Some heredocs were done like:

---
sudo bash -c "cat <<EOF > foo
...
EOF"
---

(A better way to do this is "cat <<EOF | sudo tee ..." as it retains
the usual heredoc layout in the code).

The trailing quote was throwing the matching in bash8 off and it kept
appending the next file as if it was still part of the heredoc.  To
avoid this, we check if we're still in a heredoc when we start a new
file; if so raise an error and reset the heredoc status fresh.  We
track the state of the previous file, line and lineno so we can give a
good error.

---
E012: heredoc did not end before EOF: 'cat <<EOF'
 - lib/trove: L221
---

This includes fixes for the existing problem heredocs.

A similar EOF check is to ensure the previous file ended with a
newline.

---
E004: file did not end with a newline: '$MY_XTRACE'
 - lib/neutron_plugins/embrane: L40
---

This requires only one fix

Run yum repolist commands as root

Otherwise you get yum errors like [1] when you run stack.sh as !root.
The solution is to run yum commands as root so it can access the right
certs

Move enablement of rhel6-optional repo earlier

Change 4f1fee6eae300a3384900df06ebc857e95854eb0 added the RHEL6
optional repo in fixup_stuff.sh, but it turns out that doesn't get run
until after the package prerequisites phase.  Move this into stack.sh
with the RDO repo setup.

Make python-guestfs NOPRIME & install for libvirt

The libguestfs dependency tree includes a number
of packages that we may not want or work everywhere, such as fuse.

Now python-(lib)guestfs will install from lib/nova_plugins/hypervisor-libvirt

Insecure check if keystone is up

If we start keystone with an SSL endpoint then the curl check to see if
it is running will fail because it cannot create a secure connection.
This check can be done insecurely as all we care about is that the
service has started.

Don't use --skip-redirect for cinder restart on rhel6

RHEL6 doesn't support this flag so the restart fails.  Not exactly
sure why it is required, seems unchagned from the initial
commit 67787e6b4c6f31388cbee6d83b67371b31c443d4

(found running stack.sh with -e per [1])

Unbuffer log output

* Force-flush log output so we don't lose log output in certain error cases.
* Slow down exit paths: add sleep to die(), wait until last moment to
  kill child processes (including the awk log output filter)
