[pve-devel] [PATCH docs] build: add broken-link-check

[Timothy Nicholson]

This patch adds a broken-link-check to the docs Makefile that searches
the output HTML for URLs and then tests if they are valid and do not
result in any HTTP errors. This is so that broken links can be detected
easier. Also changed occurences of ceph.com to ceph.com/en, as one
is redirected to the /en page, causing the broken-link-check to
report this URL as invalid.

This was requested by Thomas in [0]. If this is sufficient, I would
also do this for pmg-docs and pbs.
