Stephen Finucane 3a6e1e2396 doc: Rework man pages
Rework the man pages by:

- Wording the synopsis sections similarly for all commands
- Not using upper-case section names, as this is unnecessary and results
  in worse HTML output
- Formatting code and file names as literals

The 'nova-idmapshift' man page is excluded as this utility will be
removed shortly.

Synopsis
========
nova-rootwrap [options]
Description
===========
`nova-rootwrap` is an application that filters which commands nova is allowed
to run as another user.
To use this, you should set the following in nova.conf::
rootwrap_config=/etc/nova/rootwrap.conf
You also need to let the nova user run nova-rootwrap as root in sudoers::
nova ALL = (root) NOPASSWD: /usr/bin/nova-rootwrap /etc/nova/rootwrap.conf *
To make allowed commands node-specific, your packaging should only install
{compute,network}.filters respectively on compute and network nodes, i.e.
`nova-api` nodes should not have any of those files installed.
.. note::
`nova-rootwrap` is being slowly deprecated and replaced by `oslo.privsep`,
and will eventually be removed.
