Multi resource sharing

[kabicin]

Replaces multi ltpa/encryption key sharing PR

• Support multiple LTPA keys across operator versions using a decision tree where each leaf represents a resource (LTPA key) combination.
  • Use keys across versions by following instructions in and updating the internal/controller/assets/ltpa-decision-tree.yaml file and implementing reconcileLTPAMetadata() in ltpa_keys_sharing.go.
• Adds the tree folder and package tests which provides the decision tree impl. that can be extended to be used for a variety Kubernetes resources
• Adds the controllers/password_encryption_key_sharing.go which treats a password encryption key Secret (provided by user) as a namespace-shared resource, mounted into each Liberty application that sets .spec.managePasswordEncryption to true, within the same namespace.
• Securely mount and load LTPA key from /output/security/liberty-operator by using <include location="..."> in /config/configDropins/overrides
• Securely mount and load password encryption key from /output/security/liberty-operator by using <include location="..."> in /config/configDropins/overrides
