Because PCLI commands are slow and solution of
issue #34630 is likely to be quite hard, we should
at least do some optimizations to improve the
performance.

We can implement joining of commands that are
known to run together (e.g. Add + Refresh, Put +
Refresh, etc.) Joined commands can run in one
batch through PCLI, therefore there will be only
one JVM startup instead of two. Performance
improvement of a factor of two is expected. We can
also try to use the output of Add or Put command
to automatically update the status information
without the necessity to run Refresh at all. The
performance improvement is expected to be roughly
the same as if the commands would be joined
(possibly slightly better).
