double up [ for safety

The construct [ "$UNSET_VAR" -eq "1" ] will throw a bash error of
'integer expression expected' if UNSET_VAR doesn't exist. In bash
we can protect this by doubling up the brackets.

Capture QEMU logs

This commit adds support for capturing any qemu logs. We were previously
capturing the libvirt logs, but for debugging it is useful to also have
the qemu logs.

Capture apache configuration files

Capture the apache vhost files in the output from ds-g. Since we
have more than just horizon's configuration, it is useful to know
how the Apache server is running / errors in the vhost when a
check or gate job finishes.

Make one copy of grenade log files

Change 709f2349 removed the blanked 'rm' of grenade log files, but
that leaves behind several confusing entries in the final log output;
e.g [1].

---
 grenade.sh.log.2014-06-16-014311
 grenade.sh.log.2014-06-16-014311.2014-06-16-014311.summary
 grenade.sh.log.summary
 grenade.sh.txt
---

grenade.sh.txt is greande.sh.log renamed, which was a symlink to the
time-stampped file, which is no longer removed.  The summary files are
also duplicated and not directly visible because they do not have a
.log extension.

This change just keeps the grenade log and summary files.  It renames
the summary so it can be viewed, and removes the unnecessary files.
It also puts grenade's localrc in the top-level directory with the
logs, renamed to grenade_localrc

Handle proposed/ branches in test-matrix.py

We are now cutting proposed/* branches on projects. Test matrix needs to
know about them. Test proposed/foo* as if it were a stable/foo branch
when we know what foo is. If we do not know about foo fallback onto
testing with a master setup as this branch is an intermediate non
integrated release (eg swift proposed/2.0.0) which is released while
other projects are still developing on master.

As part of this change update features.yaml to teach it about juno in
prep for the upcoming juno release.

Update toggle variable for HTTPD + mod_wsgi services

Update the devstack-gate toggle variable to match the new global
toggle for running services under alternatives to HTTPD + mod_wsgi.
This toggle only affects services that default to running under
HTTPD + mod_wsgi.

The new toggle was added in: https://review.openstack.org/#/c/101611/

Stop doing tricky things with mirrors

With a bandersnatch mirror, we don't need to run mirror selection
scripts.

No more thinging in functions.sh

The debugging line of "NProc things we have <N> cpus" is badly
worded, and contains a typo. Re-word it in a way that doesn't
make people twitch.
