LU-12036 ofd: add "no_precreate" mount option
Add a mount option to disallow object creation on the OST. That
allows an OST to be mounted by the administrator without it being
immediately available for use by clients/applications. This may
be useful if the OST needs to be added to a specific pool first,
or if it is being debugged or similar.
Mount option can be disabled with the obdfilter.*.no_precreate
tunable parameter.
