wpa_cli: Improve sensitive command detection for readline history

Browse Source 
I had added flags to the every command description: just now the only
meaningful flag tells that this command has sensitive arguments and it
shouldn't be written to the disk.  I rewrote the logics for the search
for the sensitive commands: special procedure is now loops over all
commands and tries to see if command has sensitive data. [Bug 289]
