I'll enable them on "-v" or on LTP_VERBOSE=1 parameter.
Also, do we want to add it also to the shell API? -v parameter is used
nfs_lib.sh, I wonder into which to rename (-V is used for LTP version in C API,
I guess I should have add it to shell API as well).

@Andrea, I also don't see a big problem with having TVERB flag.
All of them are somehow informative, although most of them also quit.

Kind regards,
