Allow tempest to dump the ovs db

Looks like in several cases the port used by VMs are trunk port
instead of access port, would be nice if we could make those kind of
issues more visible on the gate runs.

Write DO_NOT_UPGRADE_SERVICES to grenade's localrc not devstacks

This should fix check-grenade-dsvm-partial-ncpu which currently isn't
getting DO_NOT_UPGRADE_SERVICES=[n-cpu] written to its localrc file

fix incorrect use of local

local can only be used in functions, this probably broke other
projects but no one yet complained.

add some helpfulness to our log output

this makes it more explicit what's going on in devstack gate, some
sane time ranges for operations (so people can figure out if they
are hung), and pointers to logs for each stage.

Set CEILOMETER_PIPELINE_INTERVAL to 15

New incomming tempest tests around will check the notification are correctly
collected by ceilometer. But by default the notification are processed every
600 seconds. This is too high for the gate jobs. This patch reduce this
interval to 15 seconds to allow ceilometer tempest test to succeed in
less than 15 seconds instead of 10 minutes.

Add support for running with a custom regex filter

This commit adds a new env variable, DEVSTACK_GATE_TEMPEST_REGEX to
specify a custom regex filter for running tempest. This will enable
users to specify which tempest tests get run.

Use the default home directory location for tempest.

The current location is a git checkout.  When we update that repo
and 'git clean' it, it removes any user configuration we may have
set for the tempest user (such as pip mirror locations).
