Configure boto.cfg in tempest to point to SSL bundle

The boto client uses the ca_certificate_files value in the
Boto section of /etc/boto.cfg when making an SSL client
connection. Configure that to be the devstack SSL CA bundle
so the boto tests will pass when running against an SSL or
TLS-proxy configured devstack environment.
