LUDOC-390 misc: Document shutdown procedure

This patch creates a short section to document how to stop
the entire Lustre filesystem.  Currently the manual only details
the startup procedure and how to shut down a specific target
by using umount /mnt/mnt_point.

LUDOC-372 build: Fix a condition issue with the PDF build

This patch fixes an issue with the building of the PDF
version of the manual where sections designated to use
an "Introduced in Lustre 2.X" frame were not being
processed and the entire section heading was missing.

The technical issue that was occuring during the PDF
processing is that the template in the PDF stylesheet,
style/customstyle.fo, was dropping the content passed to it.
This did not effect non-section tags, however, for section tags,
this content included the section number and heading.  It is
resolved by capturing the content passed into the condition
template and relaying it onto the textdecoration_1 template
which makes the calls to render the decoration of the text.
This fix matches what the html template uses for rendering.

This patch does not affect the build for any other
versions of the manual as a different stylesheet is used
for each format.

LUDOC-244 lfsck: Update lfsck documentation

Renamed 'Synopsis' sections to 'Usage' and swapped order with the
'Description' section. It makes more sense to see the description of a
feature before an example of its usage.

Renamed the 'Mount Options' section to 'Auto scrub' because it really
describes the auto_scrub parameter and what it does. Added a reference
in this section to the mount.lustre section where an explanation of
