This fixes some issues that we've had where commands will fail is
confusing ways after the database is rebuilt because data from before
the database was dropped is still in the memcached cache.
This fixes issue #123. Namely, the script in scripts/setup/install was
returning 0. Adding `set -e` and `set -o pipeline` causes the install
script to exit and return 1 if any part fails, including piping output
(`set -o pipeline` does this).
Most of our installation process is idempotent, but this step in
particular is not, so it's important to provide a clear error message
about how to proceed.
While the docu on https://www.zulip.org/server.html says:
```
cd /root/zulip
./scripts/setup/install
```
This script downloads the `python-django-guardian_1.3-1~zulip4_all.deb` file to current working dir (`/root/zulip` if you follow the docu), but tries to install it from /root/.
This fails obviously. So i changed the download location to /tmp/.
If there's a problem with Django settings then RMQPW would just be
empty, causing more confusing errors downstream.

Source LOCAL_DATABASE_PASSWORD and INITIAL_PASSWORD_SALT from the secrets file.
Fix the creation of pgpass file.
Tim's note: This will definitely break the original purpose of the
tool but it should be pretty easy to add that back as an option.

The manual step here is that we need to do the `puppet apply` before
pushing this commit, or `restart-server` will crash.
Previously we shut down everything in one group, which performed
poorly with supervisor's bad performance on restarting many daemons at
once. Now we shut down the unimportant stuff, then the important
stuff, bring back the important stuff, and then bring back the
unimportant stuff.
This new model has a little over 5s of downtime for the core
user-facing daemons -- which is still far more than would be ideal,
but a lot less than the 13s or so that we had before.
Here's some logs with the current setup for the tornado/django downtime:
2013-12-19 20:16:51,995 restart-server: Stopping daemons
2013-12-19 20:16:53,461 restart-server: Starting daemons
2013-12-19 20:16:57,146 restart-server: Starting workers
Compare with the behavior on master today:
2013-12-19 20:21:45,281 restart-server: Stopping daemons
2013-12-19 20:21:49,225 restart-server: Starting daemons
2013-12-19 20:21:58,463 restart-server: Done!

This reverts commit acef4c0027b77053497ef6e9f7aa4b61703205c3.
Despite the lower total downtime, this caused more user-facing downtime.

This shaves about 1.5 seconds off our restart time on ls-dev (9s ->
7.5s). Still too slow, but it's a little bit better.

We don't use apache in the main app -- only for the SSO situation --
this code was just copied from our own install script. And it caused
problems at CUSTOMER13 because they installed Apache in preparation for
the SSO integration, but restarting it failed.
