Resource specs for Init Containers

[Mortom123]

Is your feature request related to a problem? Please describe.
Some cluster providers require resources to be set on all deployments in a cluster - including init containers. Setting the requests and limits for these containers would be beneficial for their deployment

Describe the solution you'd like
A new section in values.yaml called init_container_resources having the keys of all init_containers (e.g. "wait-cluster-id") and their corresponding resources.

Describe alternatives you've considered
None

Additional context
Willing to submit a PR. :)
