Motivation for this change

• influxdb service does not start when TLS is enabled. sample configuration.nix below:

  services.influxdb = {
    enable = true;
    extraConfig = {
      http = {
        https-enabled = true;
        https-certificate = "/some-path-to-certs/full.pem";
        https-private-key = "/some-path-to-certs/key.pem";
      };
    };
  };

• also removed unnecessary quotes for the curl command
