and configuration used by the Nova libvirt driver. Ensures a functional
libvirt setup across distributions.

Set VIRSH_DEFAULT_CONNECT_URI in Ironic scripts

Ironic setup scripts that interface with virsh should default to always
connecting to the 'qemu:///system' URI.  Adds LIBVIRT_CONNECT_URI that
ends up exported as VIRSH_DEFAULT_CONNECT_URI in scripts that require
it.

Allow sudo access without a controlling terminal

Ironic setup uses some external scripts that use sudo but they
are not called with a TTY.  This patch allows STACK_USER sudo
access without a controlling terminal.

Special casing for Ironic VIRT_DRIVER in exercises

Ironic on Devstack does not currently suppport security groups or
anything volume related.  Add some special casing so exercises can
be run without error against the Ironic driver.

Parse Ironic packages files/{apts, rpms}/ironic

When VIRT_DRIVER=ironic, make sure devstack picks up packages listed in its
respective packages file.  These were previously missed unless "ironic" was
explictly added to the enabled services.  This ensures required packages
are installed for any of the ir-* services.

Disable ceilometer's swift middleware

This middleware is spamming rsyslog with rabbitmq debug logs, making
this middleware practically unusable in combination with rsyslog. Because of
this, the rsyslog logs now account for 35% percent of the logs we store
in logstash. Until the underlying problem is solved disable the
offending code.

move the rsyslogd restart

it's not clear why swift start is the place where an rsyslogd start
is happening, we should really only make this change when we actually
change a file on disk.

Also, use rsyslogd's -HUP signal directly instead of the system init
scripts which are typically doing a stop and start, and apparently
racing under some circumstances.

but we lost this somewhere.
