feat(deployment): support further initContainers

Browse Source 
The following patch intoduce the dictionaries pre and postExtraInitContainers.
The dictionaries can be used to specify further initContainers before and after
the gitea initializing process. For example:

```yaml
postExtraInitContainers:
- name: foo
  image: docker.io/library/busybox:latest
preExtraInitContainers:
- name: bar
  image: docker.io/library/busybox:latest
```
