Remove tox_install.sh and just pass -c in toxpike-eolstable/pike

The tox_install.sh scripts are there to enable dealing with constraints
support. All of that can be accomplished directly, it turns out, by
simply adding the -c line to the requirements list.

Remove tox_install.sh and just set constraints directly.

Conflicts:
	tox.ini

NOTE(stephenfin): Conflicts are due to some additional changes
introduced to tox in stable/queens before this patch. This patch is
required because 'tox_install.sh' uses curl w/o -L switch so it fails to
account for redirects that are now in place for backward compat with
git.openstack.org.
