Fix the section reference in ch_ops_maintenance

The last line of "Total Compute Node Failure" section in "Maintenance,
Failures, and Debugging" chapter refers to "After a compute node Reboots"
for the detail of volume re-attaching. However, volume re-attaching is
described in "Volumes" section instead of "After a compute node Reboots".

This commit also fixes typo in ch_arch_network_design.xml.

Update references with new Mailing List location

Yesterday, openstack@lists.launchpad.org was migrated with
all users to openstack@list.openstack.org.

This patch updates references to the old mailing list with the
new, to ensure that people encountering them don't accidentally
try and join the old list!
