ERA-60184 : Name based resolution

[sasikanthmasini]

Jira ticket link : ERA-60184

Implementation as part of the PR:

1. Cluster Name Resolution: Requires the NDB clusters API endpoint. If not available, cluster name resolution will fail with a clear error message.
2. Snapshot Name Resolution: Requires the source database's time machine ID. The implementation automatically fetches this when resolving snapshot names.
3. Unique Names: This feature only works for entities that have unique names in NDB. If NDB doesn't enforce unique names, the operator cannot distinguish between entities with the same name.
4. Backward Compatibility: Existing specs using UUIDs continue to work. The operator accepts either UUIDs or names.

Most of the changes look good. Please check on below points:

• image name and tag for controller
• run go fmt (format) once for all go files.

Also please update PR description with thorough testing details done for provisioning/cloning DBs using operator logic (not automation test logic)

[shivaprasadmb]

please keep this as

  newName: ghcr.io/nutanix-cloud-native/ndb-operator/controller
  newTag: v0.5.3

because the github workflow will create a new container image using these values.
