Description

Currently, the Cloudflare provider in external-dns can only read the Cloudflare API token from an environment variable named $CF_API_TOKEN. Users could populate $CF_API_TOKEN with a Kubernetes Secret. But a more flexible way is to read the Cloudflare API token from file. For example, if the user stores the secret (Cloudflare API token) in HashiCorp Vault, and uses vault agent sidecar to provide the secret to external-dns container through a shared volume backed by memory, allowing the Cloudflare provider in external-dns to read this secret file would be superb.
