[CPREQ-7712] Backward-compatible lightweight enrichment of connections

[ilia1243]

Description

• The result of InventoryOnlyPatchs is not preserved on nodes.
• kubemarine do runs full enrichment and thus cannot be used before migration.
• PR depends on [CPDEV-100505] Always dump finalized inventory for all procedures except do #629

Solution

• Implement backward-compatible, lightweight enrichment of connections.
• Restrict sections that can participate in enrichment of connections and that can be referred to during jinja compilation.
• Gathering of nodes' data, preserving of the inventory, and kubemarine do use the new lightweight inventory.
• globals.nodes.boot.timeout is moved to node_defaults.boot.timeout for the lightweight enrichment to do not depend on globals.

Breaking changes

• No longer possible to run InventoryOnly patches without access to the cluster.
• globals.nodes.boot.timeout is moved to node_defaults.boot.timeout
• Restricted compilation of connections
  • Dynamic variables in nodes, node_defaults, gateway_nodes, procedure_history, values, cluster_name sections
    no longer can refer to other sections.
  • globals.yaml are not available in the above sections.

How to apply

Run kubemarine migrate_kubemarine --force-apply boot_timeout_per_node

Test Cases

TestCase 1

Steps:

1. Configure inventory overriding the globals.nodes.boot.timeout property.
2. Run kubemarine migrate_kubemarine --force-apply boot_timeout_per_node

ER:

1. The property is moved to node_defaults.boot.timeout
2. Initial and final inventory are preserved on nodes.

TestCase 2

Steps:

1. Run kubemarine do using inventory of very old, no longer supported format.
