Ansible will soon write the node id to `identity.toml` in the work dir for new pageservers. On the pageserver side, we read the node id from the identity file if it is present and use that as the source of truth. If the identity file is missing, cannot be read, or does not deserialise, start-up is aborted. This PR also removes the `--init` mode and the `--config-override` flag from the `pageserver` binary. The neon_local is already not using these flags anymore. Ansible still uses them until the linked change is merged & deployed, so, this PR has to land simultaneously or after the Ansible change due to that.
