For the tempest plugin install inside the tox venv to hold we need to ensure that it's the last thing run that touches the tox venv before devstack ends. Otherwise there is a chance we'll recreate the venv in a later step of installing and configuring tempest. This commit moves the plugin installation into it's own function and calls that function as last phase of the tempest setup to make sure it runs last.

Extras Hooks
The extras.d directory contains project dispatch scripts that are called
at specific times by stack.sh, unstack.sh and clean.sh. These hooks are
used to install, configure and start additional projects during a DevStack run
without any modifications to the base DevStack scripts.
When stack.sh reaches one of the hook points it sources the scripts in extras.d
that end with .sh. To control the order that the scripts are sourced their
names start with a two digit sequence number. DevStack reserves the sequence
numbers 00 through 09 and 90 through 99 for its own use.
The scripts are sourced at the beginning of each script that calls them. The
entire stack.sh variable space is available. The scripts are
sourced with one or more arguments, the first of which defines the hook phase:
override_defaults | source | stack | unstack | clean
override_defaults: always called first in any of the scripts, used to
override defaults (if need be) that are otherwise set in lib/* scripts
source: called by stack.sh. Used to set the initial defaults in a lib/*
script or similar
stack: called by stack.sh. There are four possible values for
the second arg to distinguish the phase stack.sh is in:
arg 2: pre-install | install | post-config | extra
unstack: called by unstack.sh
clean: called by clean.sh. Remember, clean.sh also calls unstack.sh
so that work need not be repeated.
The stack phase sub-phases are called from stack.sh in the following places:
pre-install - After all system prerequisites have been installed but before any
DevStack-specific services are installed (including database and rpc).
install - After all OpenStack services have been installed and configured
but before any OpenStack services have been started. Changes to OpenStack
service configurations should be done here.
post-config - After OpenStack services have been initialized but still before
they have been started. (This is probably mis-named, think of it as post-init.)
extra - After everything is started.
