Add checks for blocks operations and other changes

* Add ISCSIOPS and FCPOPS checks type similar to CIFSOPS
* New -V option sets SNMP version (needs 2c for reading 64bit values)
* New -I option return every time OK state (if you needs only performance data)
* redesign help message and append examples
* nagioscache files create only if check needs caching
* each check has own *.nagioscache file (when I using multiple tests I get
  inexact values of performance data)
* change version to 1.2
