netdata: do not send anonymous statistics by default.

Netdata is sending anonymous statics data to Google by default.

Disabling this by default in the recipe by adding the
 .opt-out-from-anonymous-statistics file in the netdata config
directory.
@see: https://learn.netdata.cloud/docs/agent/anonymous-statistics#opt-out
