----------------------------------------------------------------------
[~pifta] [~erose] Will this conditional action be executed irrespective of the
"{{{}pre-finalized" state{}}} of OM ?
IMHO to disallow any operations(read/update) on a FILE_SYSTEM_OPTIMIZED("FSO")
bucket by a {{{}pre-FSO client(old version client){}}}at any state of OM(either
pre-finalized or finalized state) .
Expected behavior of FSO: Only a {{new client}} can talk to FSO bucket.

> Currently, the upgrade framework provides annotations that can be applied to
> RPC endpoints to fail calls when the cluster is pre-finalized for a certain
> layout version. Features like EC and FSO may add parameters to existing
> endpoints, instead of adding new endpoints, and the request only needs to be
> blocked or modified if certain arguments are passed in. This Jira proposes
> adding annotations for conditional failure based on the arguments supplied
> and the cluster's metadata layout version. Pluggable actions given to the
> annotation could fail the request or modify the arguments before proceeding.
