feat: add option to configure ressource requests und limits on init containers

[sam0r040]

This PR adds the option initContainer.resources to configure resource requests and limits for the init containers. This is necessary in environments that require resource limits to be set for all containers.

All pre-defined init containers receive the same configuration as there is no specific configuration yet and both are basically performing the same task.

@gitkent I was not aware that I should increase the chart version as part of the PR and increased it just now. Is there anything else I can do to move this forward?

@sam0r040 no worries. Can you please check the CI build again? It failed on linting.
