Ceph Developers: obsolete links for Ceph basics

[laimis9133]

The Ceph Developers webpage has a section at the very bottom titled "Ceph guides, tips and tricks". Seems that the two links for Ceph Basics there have become obsolete:
Ten essential Ceph commands to manage your cluster
Top five mistakes to avoid in your Ceph storage cluster

They bring to webpages with not valid certificates and at least Safari browser is not able to open them at all.

The "Ten essential Ceph commands to manage your cluster" seems to be moved to the softiron blog at this location: https://blog.softiron.com/engineering/10-essential-ceph-commands-for-managing-any-cluster-at-any-scale/
The "Top five mistakes to avoid in your Ceph storage cluster" is available only through Amazon here: https://s3.amazonaws.com/cdn-media.softiron.com/doc/SoftIron_Avoid+these+5+Common+DIY+Ceph+Mistakes.pdf

These links should be updated or maybe the whole section needs a rewamp.
