Description

This is secondary to #4546. Please review #4546 first.

This relates to the proposal "Behind the scenes conversion from V6 to V7" from #4493.
This converts the V6 config instances to V7 config instances "behind the scenes". This allows to save a lot of duplicate implementation regarding to privilege evaluation and possibly also further logic.

As an additional benefit, this makes it possible to use SecurityDynamicConfiguration<> instances in a generically type-safe manner. So far, one usually needs to use SecurityDynamicConfiguration<?> instances and do unsafe casts.

This only touches the runtime representation of the configuration. If there's a V6 configuration in the configuration index, it remains untouched. The possibility to update configuration in V6 format will remain.

This is only for OpenSearch 2.x. For the OpenSearch main branch, #4546 removes V6 config support alltogether.

Behind the scenes conversion

Some more detail on what is changed by this PR:

The configuration architecture consists of these levels:

  1. JSON documents in the configuration index
  2. ConfigurationRepository which manages SecurityDynamicConfiguration<> instances which contain as entry instances of org.opensearch.security.securityconf.impl.v6.RoleV6, org.opensearch.security.securityconf.impl.v6.RoleMappingsV6, org.opensearch.security.securityconf.impl.v7.RoleV7, org.opensearch.security.securityconf.impl.v7.RoleMappingsV7, etc.
  3. DynamicConfigFactory which consumes SecurityDynamicConfiguration<> instances and creates ConfigModel and DynamicConfigModel instances. If it finds V6 classes in SecurityDynamicConfiguration<>, it creates ConfigModelV6 instances, if it finds V7 classes, it creates ConfigModelV7 instances.
  4. The ConfigModelV6 and ConfigModelV7 classes contain business logic which evaluates roles and permissions.
  5. This is used by PrivilegesEvaluator.

This PR changes the architecture at level 2:

  1. The JSON documents in the index do not change
  2. ConfigurationRepository is changed in this way: If it finds V6 instances like org.opensearch.security.securityconf.impl.v6.RoleV6, it auto-converts these to V7 instances like org.opensearch.security.securityconf.impl.v7.RoleV7. The V7 classes already have functionality for that which is already used for the securityadmin migration command.
  3. This makes the distinction of V6/V7 on all layers below unnecessary. DynamicConfigFactory does no longer need a distinction between two config versions.
  4. ConfigModelV6 becomes redundant.
  5. As PrivilegeEvaluator consumes the super interface ConfigModel, it does not notice anything about this change.

Thank you @nibix! Left a few comments. This change looks good to me. This will greatly simplify the security codebase to only have to keep track of the v7 models.

@DarshitChanpura @willyborankin @derek-ho @peternied Could we get one more review on this? This change helps pave the way forward for Optimized Privileges Evaluation as it simplifies the code greatly to only depend on one version of the models.
