With this update, enabling `enable_experimental_unrecoverable_data_corrupting_features` is no longer required to use Beast.

Description Karun Josy 2019-09-06 11:24:54 UTC 
* Description of problem:

RHCS 3.3.0 release notes say that radosgw beast frontend is now fully supported:
"The Beast.Asio web server front end for the Object Store Gateway (RGW) is now GA and a fully supported option."

However, to start using Beast the 'experimental-data-corruption-may-happen feature flag' is still required.

This feature is marked as experimental, which means it
 - is untested
 - is unsupported
 - may corrupt your data
 - may break your cluster is an unrecoverable fashion
To enable this feature, add this to your ceph.conf:
  enable experimental unrecoverable data corrupting features = rgw-beast-frontend

This is documented in our Object Gateway Guide, but this kind of sends conflicting messages to customers if it can be actually used in production or not. Is there any specific reason we need to continue to use this flag or can we remove it in the next release?
