Drop kebab-case configuration notation (#196)

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.

Fixes: #188

 ### Metrics and profiling
 
 A Prometheus `/metrics` endpoint on the `HTTP_PORT` and `pprof` profiling endpoints on port 6060 can be enabled under `gitea`. Beware that the metrics endpoint is exposed via the ingress, manage access using ingress annotations for example.
