chore: reduce redis-cluster pods and move HA out of "experimental" state (#565)
The pod reduction for `redis-cluster` should help users seeking for a Gitea deployment with less pods. Users seeking for a minimal deployment are further advised to follow https://gitea.com/gitea/helm-chart#user-content-single-pod-configurations. HA is working fine in the provided configuration and should be moved out of the "experimental" state given that there were no reports of Gitea malfunctioning reported to HA usage in recent months/since v9 release.

⚠️ **EXPERIMENTAL** ⚠️

Since version 9.0.0 this chart has experimental support for running Gitea and it's dependencies in a HA setup.
|
||||
The setup is still experimental and care must be taken for production use as Gitea core is not yet officially HA-ready.
|

Since version 9.0.0 this chart supports running Gitea and it's dependencies in HA mode.
|

Care must be taken for production use as not all implementation details of Gitea core are officially HA-ready yet.
|
||||
|
||||
Deploying a HA-ready Gitea instance requires some effort including using HA-ready dependencies.

See the [HA Setup](docs/ha-setup.md) document for more details.

All components (in-memory DB, volume/asset storage, code indexer) used by Gitea must be deployed in a HA-ready fashion to achieve a full HA-ready Gitea deployment.
|

The following document explains how to achieve this for all individual components.

|
|||
- `gitea.config.cache.ADAPTER`: `redis`
|
||||
- `gitea.config.cache.HOST`: `<your redis connection string>`
|
||||
|
||||
By default, the `redis-cluster` chart provisions three standalone master nodes of which each has a single replica.
|
||||
To reduce the number of pods for a default Gitea deployment, we opted to omit the replicas (`replicas: 0`) by default.
|
||||
Only the minimum required number of master pods for a functional `redis-cluster` deployment are provisioned.
|
||||
For a "proper" `redis-cluster` setup however, we recommend to set `replicas: 1` and `nodes: 6`.

## Object and asset storage

Object/asset storage refers to the storage of attachments, avatars, LFS files, etc.
