Merge #227

227: Add initContainer support r=brunoocasali a=zfalen

# Pull Request

## Related issue
Fixes #226

## What does this PR do?
- Enables support for `initContainers` consistent with enablement for `containers` and `volumes` etc

## Example
I was able to create an `initContainer` pattern that pulled a `.dump` file from S3 and mounted it into the Meili pod using the following values:

```
initContainers:
  - name: aws-copy
    image: amazon/aws-cli
    envFrom:
      - configMapRef:
          name: env-with-s3-creds
    command:
      - "/bin/sh"
      - "-c"
      - aws s3 cp "s3://$S3_BUCKET/meilisearch_dumps" /meili_data/dumps --recursive
    volumeMounts:
      - name: meili-dumps
        mountPath: /meili_data/dumps
volumes:
  - name: meili-dumps
    emptyDir: {}
volumeMounts:
  - name: meili-dumps
    mountPath: /meili_data/dumps
environment:
  MEILI_IMPORT_DUMP: /meili_data/dumps/myClonedDumpFile.dump
  MEILI_ENV: development
  MEILI_MASTER_KEY: someReallyCoolKeyAlsoWookiesRule
  MEILI_NO_ANALYTICS: true
```
