Eloy Lafuente (stronk7) d676a8114e MDL-71420 environment: Add some strategic comments and todos.
This isn't really a deprecations where something is replaced
by another and all uses must adapt to. Instead it's just a
fallback functionality that will stop working in Moodle 4.2.

Because of that, I've tried to add TODO/@todo comments to
the places that will need to modified, always pointing to
MDL-71421 that is where the removal will happen.

Also, haven't added any debugging() output, after thinking
a lot about it, because this isn't anything that developers
can be using but a internal implementation detail (a fallback)
that we want to remove in some versions.

This script manually creates a secure key within the secret data root folder (configured in

In normal use Moodle automatically creates the key; this script is intended when setting up
a new Moodle system, for cases where the secure folder is not on shared storage and the key
may be manually installed on multiple servers.
