Calculate "checks per second"

[widhalmt]

Calculate how many checks per second are executed within the whole setup.

This could make installations better comparable. But we should not get fooled by missing details:

• This doesn't take into account that plugins can have very different load characteristics. Running thousands of check_icmp will use significantly lower resources than check_nwc_health
• This would not check on how many hosts the checks are distributed. Some setups run all checks on their masters other spread them over many satellites

I still think it's a good idea to have this metric because it can make setups comparable on "how well" they are performing when they keep to best practices. When setups of similar size have very differing performance one would at least know that it's not just wrongly sized. This can help with developing more best practices, too.
