----------------------------------
[~larsh]
The main motivation for this option are the following
1) Sometimes customers want to retain hfiles in the archive directory for a day
or so after deletes, as a backup. So they configure the cleaner to run every
24hours to cleanup the files. This obviously takes up space. However not all
tables require this feature and some can be deleted from disk as soon as the
table is deleted / compactions are done. So this patch helps such situations
where they can mark skip_archive for such test tables and not let it pass
through archive so that they can reclaim the space immediately after deletion.
2) Avoid unnecessary NN operations for not-so-useful tables. If we move to the
archive, instead of N file delete calls, we make N file moves and then do N
file delete calls. Depending on the table size N can be very huge and we can
avoid putting pressure on NN.

> Currently HFileArchiver is always called when a table is dropped.
> A configuration option (either global or per table) should be provided so
> that archiving can be skipped when table is deleted.
