Operator Capture CRD is missing configuration options

**Is your feature request related to a problem? Please describe.**
Currently the Capture CRD / Job only offers a limited set of configuration options with many hard coded values like resource usage / limits or that it requires a `hostpath` volume instead of ephemeral volume like `emptyDir`.

See https://github.com/microsoft/retina/blob/07550e771147a91b6f56f17259bd88c9fff869f1/pkg/capture/crd_to_job.go

**Describe the solution you'd like**
Offer options to define default values for the Capture Job during deployment e.g. through the Helm Chart and additional options to overwrite these defaults with the Custom Ressource if needed for most of the configuration parameters of the Capture Job.
