Rename tackle-windup data volume => maven

[jortel]

windup_fqin: "{{ lookup('env', 'ADDON_WINDUP_IMAGE') }}"
windup_name: "windup"
windup_component_name: "addon"
windup_service_name: "{{ app_name }}-{{ windup_name }}-{{ windup_component_name }}"
windup_data_volume_name: "{{ windup_service_name }}-data"
windup_data_volume_size: "100Gi"
windup_data_volume_claim_name: "{{ windup_service_name }}-volume-claim"
windup_container_requests_cpu: "1"
windup_container_requests_memory: "2Gi"

Replace with something like:

windup_fqin: "{{ lookup('env', 'ADDON_WINDUP_IMAGE') }}"
windup_name: "windup"
windup_component_name: "addon"
windup_service_name: "{{ app_name }}-{{ windup_name }}-{{ windup_component_name }}"
windup_container_requests_cpu: "1"
windup_container_requests_memory: "2Gi"

maven_name: "maven"
maven_data_volume_size: "100Gi"
maven_data_volume_claim_name: "{{maven_name}}-volume-claim"

The (2) addons (admin, windup) will need to have the {{maven_name}}-volume-claim.

Questions:

1. What is:

windup_service_name: "{{ app_name }}-{{ windup_name }}-{{ windup_component_name }}"

2. Why do all the claim names have a claim suffix? It's unconventional and k8s resources are already qualified by kind.
They all also seem to contain the work "volume" which seems redundant since a PVC isA "volume claim" by definion.
