Merge crab rest, log pipeline, and serviceaccount manifests together in single helm chart

[novicecpp]

I would like to commit the new serviceaccount for CI to CMSKuberentes but I do not know where to put it. Also, the crab's logstash manifests is in different place.

After discuss with @arooshap, she suggested to put everything together in single helm chart, helm/crabserver, and use value flags to render specific resources groups.

We have 3 resource group:

• crabserver manifest for crab rest.
• log pipline, which have logstash and crab's filebeat.
• new CI serviceaccount that need cluster admin permission.

For example, the values-testX.yaml only for render crabserver-related manifests:

environment: "test"
enabled: true
image:
  tag: "pypi-test12-manual1"

To render log pipeline and CI serviceaccount (e.g., values-admin.yaml), the value file will look like this:

environment: "preprod"
enabled: false
logPipeline:
  enabled: true
ciServiceAccount:
  enabled: true

This will be easier for cluster admin to maintain all our services.
And for us, we only need to focus on modifying the crabserver resourec group, e.g., adding a new canary deployment.

@belforte @aspiringmind-code I would like to hear your comment about a new config directory structure.

• config/{test,preprod,prod}/config.py for rest config config.py (move from crab-secrets/kuberentes)
• config/{test,preprod,prod}/logstash.conf for logstash config

Here is the full directory structure:
