[ClusterLabs] New ClusterLabs wiki

[Ken Gaillot]

Hi all,

The ClusterLabs project manager is now publicly viewable, without
needing a GitHub account:

  https://projects.clusterlabs.org/

Anyone can now follow issues tracked there. (Issues created before the
site was public will still require an account unless someone updates
their settings.)

The site has a simple built-in wiki, so to reduce sysadmin overhead, we
have moved the ClusterLabs wiki there:

  https://projects.clusterlabs.org/w/

The old wiki.clusterlabs.org site is gone, and redirects to the new
one. A lot of the wiki pages were more than a decade old, so they were
dropped if they didn't apply to current software and OSes.
