With release 5.0.0 there are so many deprecations and breaking changes
that it is probably a good way to assist the users with values migration
before breaking their environments.
This adds another template file that doesn't render anything but ensures
the removal of dropped or deprecated settings from customized values
files.
For when it is necessary, this check can be disabled via new setting
`checkDeprecation`.

With the result of PR #239 it is much easier to provide additional values to the _app.ini_ configuration from different sources.
These changes adds an _additionalConfigSources_ field where the users can define such sources. This enables the users to choose
on their own whether to store values in _values.yaml_ or load them from Kuberetes Secrets or ConfigMaps.

Hello !
I'm using the new Helm chart (5.x) and I really like the new configuration mechanism. 👍
I would like to contribute the following enhancement.
## The problem I want to solve
I'm trying to deploy Gitea in a Kubernetes shared platform and I need to make sure each instance is running as a different user so that in case of container escape, the risk of data leak is minimized.
Additionally, on my platform (OpenShift), arbitrary users (such as uid 1000 for Gitea) are not allowed.
The current helm chart does not allow me to achieve this because:
- the container security context is configurable only for the main container. The security context of init containers cannot be specified.
- a fixed uid is hard coded
- a fixed fs group is hard coded
Also, the securityContext of a pod and the securityContext of a container do not accept the same options.
- https://kubernetes.io/docs/reference/generated/kubernetes-api/v1.19/#podsecuritycontext-v1-core
- https://kubernetes.io/docs/reference/generated/kubernetes-api/v1.19/#securitycontext-v1-core
## How I'm solving the problem
I split the `securityContext` (values.yaml) in two: `containerSecurityContext` and `podSecurityContext`. The containerSecurityContext applies to all containers (init and main) in order to be consistent with file permissions.
The behavior for existing deployments is unchanged:
- fsGroup 1000 is the default value for the podSecurityContext variable
- the "configure-gitea" init container uses the uid 1000 unless otherwise stated in the containerSecurityContext
- the main container is using the existing securityContext variable when defined in order not to break existing deployments and uses the new containerSecurityContext variable if not.
This approach is well tested: it is used consistently on bitnami's Helm charts.
## How I tested
I tested both root and rootless variants on a Kubernetes 1.22, as well as rootless variant on OpenShift 4.7.
**rootless variant on Kubernetes**:
```yaml
podSecurityContext:
fsGroup: 10001
containerSecurityContext:
allowPrivilegeEscalation: false
capabilities:
drop:
- ALL
add:
- SYS_CHROOT
privileged: false
runAsGroup: 10001
runAsNonRoot: true
runAsUser: 10001
extraVolumes:
- name: var-lib-gitea
emptyDir: {}
extraVolumeMounts:
- name: var-lib-gitea
readOnly: false
mountPath: "/var/lib/gitea"
```
**rootless variant on OpenShift**:
```yaml
podSecurityContext:
fsGroup: null
containerSecurityContext:
allowPrivilegeEscalation: false
privileged: false
runAsNonRoot: true
runAsUser: 1000790000
extraVolumes:
- name: var-lib-gitea
emptyDir: {}
extraVolumeMounts:
- name: var-lib-gitea
readOnly: false
mountPath: "/var/lib/gitea"
```
Let me know if something is unclear.

Currently there are two different styles for defining both ldap and oauth configuration in _values.yaml_ file: `camelCase` and `kebab-case`.
Supporting both styles created multiple regressions in the past.
⚠️ BREAKING ⚠️
---------------
These changes completely remove any support for `kebab-case` notation in _values.yaml_ in favor of `camelCase`. Configuration keys must use `camelCase`.
Only exception are Kubernetes resource keys for annotations or labels.

These changes rewrite the init script to be error aware, informative and have a bit more security awareness.
During rewrite several hidden bugs could be identified and fixed, such as:
- LDAP configuration options interpreted by the shell before passed to command
- Finding multiple ldap ids instead of one during lookup when their names are almost identical
e.g. `_my-ldap-auth` and `my-ldap-auth`
- Properly filter auth sources by their types to prevent unintended type converting attempts that fail
In addition to that the script is a bit cleaner. Some commands do not exist anymore and would cause false-positive errors during script execution.
Helps for: #149

The `HOME` path is not persistent when using the rootless image, so the
`.gnupg` folder isn't either. Since the chart always used `/data/...` as
mount point for storage of all kinds, it is a minimal impact to just
relocate the dynamic `$HOME/.gnupg` folder location to the persistent
`/data/git/.gnupg`. This is where the signing keys are stored when
running root based environments. Doing so will
- allow migrations between both image variants
- persist signing keys for rootless environments

I've noticed that the commented `securityContext` is not really useable with the rootless image due to different directory structure compared to the default image.
Important for the `readOnlyRootFilesystem` is to declare the `TMPDIR` environment variable, so that the tmp directory (which is readonly in this case) won't be used. Instead, another writeable directory can be used.
Another thing is the explicit hint that all these security options cannot be used with the default (root-based) image, because of its design.
~~Although this PR would fix the referenced issue, I am not totally happy with the current implementation. It would be more straight forward to use the same mount points for both image variants. Unfortunately, this is not possible right now due to hard coded paths in the default (root) image startup scripts.~~
~~Anyone have suggestions on how this could be more simple?~~
-------
**Sum-up:**
As mentioned in Discord, this PR tried to make too many changes. The necessary changes made in 1f331a7e6577fc798196a84a957330aca0d663cd will fix an error that occurs due to restricted access to the `/tmp` directory in a rootless image with all the `securityContext` options enabled.
I also updated the default image to 1.14.2.
