feat(cf-common): add extra volumes and volumeMounts from globals

[mikhail-klimko]

What

Adding option to merge volumes and volumeMounts from globals.

global:
  volumes:
    global-ca-cert:
      ...
  container:
    volumeMounts:
      global-ca-cert:
        path:
          ...
  
volumes:
  ca-cert:
    ...

container:
  volumeMounts:
    ca-cert:
      path:
      ...

Whatever is specified in default values takes precedence over globals

Why

Need to pass volume and mount with custom CA certs for ANZ for almost every classic microservice.
