Add the possiblity to specify core-only secrets in the helm chart

[sbjzn]

Is your feature request related to a problem? Please describe. I am currently using the coreEnvs to fetch and set OAuth secrets, however these secrets are also exposed to privileged services.

Describe the solution you'd like A way to specify environment variables that are only applied to the core components, and no services at all.

Describe alternatives you've considered I can't find any other way to do this other than modifying the helm chart.

Additional context This comment in values.yaml is misleading, the wording should probably be changed to mention that the variables are exposed to privileged services.

# Extra environment variables, mounts, and volumes shared by all core containers
# Any environment variables set here can be used in the value strings of any
# field under the configuration.* block. This is the proper way to pass a secret
# to the assemblyline core components. These values won't be passed to analysis
# services.

This should be patched in 4.5.0.37.
