Migrate from bitnamicharts/valkey (and bitnamicharts/valkey-cluster) to the official Valkey Helm chart (https://valkey.io/valkey-helm, v0.10.0).
Changes:
- Remove valkey-cluster dependency and all related values, templates, and unit tests
- Update valkey dependency to use https://valkey.io/valkey-helm
- Adapt _helpers.tpl (valkey.dns, valkey.port, valkey.servicename) to the new chart's service naming and value structure
- Update values.yaml to match the new chart's configuration schema (auth.aclUsers instead of global.valkey.password, service.port instead of primary.service.ports.valkey, dataStorage instead of
primary.persistence)
- Update all affected unit tests
- Update README documentation
BREAKING CHANGE: valkey-cluster support has been removed. Users previously relying on valkey-cluster must migrate to standalone valkey or an external Redis-compatible service. The valkey values structure
has changed: `valkey.global.valkey.password` is now `valkey.auth.aclUsers.default.password`, and `valkey.primary.service.ports.valkey` is now `valkey.service.port`.
