I'm a new Ceph user and I did initially try the interactive mode, hoping it
would help me discover the various commands I could run and work through their
output.  TBH I found it pretty useless for that purpose - no "help" command, no
tab completion, no history or line editing, no way to ask "what options can I
use next".  Even the "10 closest matches" output doesn't include the brief
command descriptions that "ceph --help" has.

In its current form I don't think dropping it would be a big loss.  Plus
improving it enough to be helpful would be a big project and doesn't provide
that much value over the regular CLI.

Thanks,
Mark
