> The options to filter datanodes in commands like {{ozone admin datanode
> usageinfo}} and {{ozone admin datanode decommission}} should be consistent.
> Right now there are divergences among the various commands, including mixed
> use of {{\-\-id}} or {{\-\-uuid}} to filter by datanode ID, and commands that
> only support selection based on host name.
> Create a PicoCLI mixin that provides a standardized set of node selection
> options that can be re-used for all relevant commands:
> * {{--node-id}} for datanode UUID
> ** This is consistent with ID based selection for OM and SCM commands like
> {{{}ozone admin om decommission{}}}.
> ** {{--id}} is confusing with the SCM service ID option that some commands
> also take, which has the short form {{{}-id{}}}.
> ** {{--uuid}} couples the flag to the ID generation algorithm unnecessarily.
> * {{--hostname}} for datanode host
> * {{--ip}} for datanode IP address
> Commands using other selection flags will need to have those flags hidden and
> deprecated from the CLI while left in place in the code to maintain
> compatibility.
