Don't override the versions is server-vars.yml.

Having `--tags deploy` be part of the ansible-playbook call
that `/edx/bin/update` makes is not intuitive.  It's broken
us a few times recently and I don't think the benefit it
provides is worth the cost and confusion.  I feel that anyone
who wants to use tags will know how to do it without using
`/edx/bin/update`.

This modifies the edx_ansible role to dump a clean var
file on disk that can be used for subsequent update runs
so that config vars will not be lost

also changes the ansible tmp directory to /var/tmp which is a better
location than using $HOME (used for debugging mostly)
