Subject: check_snmp: refactoring + fixes

This commit moves the state retention logic to check_snmp as it is only
used there and I do not want it to be used at all, so it doesn't get a
place in the lib.

Otherwise this adapts tests and fixes the rate computing in the
refactored version of check_snmp.
Also fixes some bugs detected with the tests
