Purge Fedora getting started of old info

Remove all of the old tools/openstack related info from
the on_fedora docs - the best source of documentation for
Fedora is now the RDO docs (for Heat RPM package installs),
or the on_devstack guide for development installs.

Disable lazy translation

Late in the Havana cycle bug 1225099 was found in the lazy
translation code, and to be safe it was decided to disable lazy
translation for Havana.  This change does that.

heat_keystoneclient: Fix consuming trusts via v2 API

Contrary to my understanding when I first wrote this code, it is
possible to consume trusts (ie get a trust scoped token) via the
v2 keystone API.  So this patch reworks the heat_keystoneclient
so we:
- Consume trusts via the v2 client (so we can access the ec2tokens
  extension which is v2-only)
- Only create a v3 client when required (when creating or deleting
  a trust), so we minimise the requests to keystone.
- Similarly it's only necessary to create the v2 client when creating
  the client object if we need to consume a trust
- When a trust is found in the context, we always consume it
- Don't modify the request context, as this has undesired side-effects
  if the context is subsequently used to perform actions which require
  obtaining a keystone token, instead create a context containing a
  trust_id and trustor_user_id when the stack is stored.

Note this change depends on this patch to python-keystoneclient:
https://review.openstack.org/#/c/48462/, so consuming trusts won't
work unless a version of keystoneclient including this change is
used.
