Subject: [PATCH] limit jinja2 version to <2.9

Ansible 2.2.1 requires jinja2<2.9, see <https://github.com/ansible/ansible/blob/v2.2.1.0-1/setup.py#L25>,
but without explicit limiting upper jinja2 version here pip ignores
Ansible requirements and installs latest available jinja2
(pip is not very smart here), which is incompatible with with
Ansible 2.2.1.
With incompatible jinja2 version "ansible-vault create" (and probably other parts)
fails with:
  ERROR! Unexpected Exception: The 'jinja2<2.9' distribution was not found
  and is required by ansible
This upper limit should be removed in 2.2.2 release, see:
<https://github.com/ansible/ansible/commit/978311bf3f91dae5806ab72b665b0937adce38ad>
