[Feature]: Add possibility to specify defaultMode in extraConfigmapMounts

[pavel-luhin]

Requirement

As a jaeger helm chart user, I want to pass initial elasticsearch index templates script via configmap.

Problem

Jaeger helm chart does not allow me to specify defaultMode: 0744 to make my script from configMap executable.

Proposal

Add possibility to specify defaultMode in extraConfigmapMounts, to make it look like this:

    extraConfigmapMounts:
      - name: init-script
        mountPath: /opt/script.sh
        subPath: jaeger-elastic-index-templates.sh
        readOnly: true
        configMap: configmap-jaeger-elasticsearch-init-script
        defaultMode: 0744

As a temporary workaround it is possible to add this script directly to init container like this

  agent:
    image: jaegertracing/jaeger-agent
    initContainers:
      - name: jaeger_es_index_templates_creator
        image: curlimages/curl:7.87.0
        command: ["/bin/sh"]
        args:
          - '-c'
          - |
            echo "Do script here"
