Prevent zevent list from consuming all of kernel memory
There are a couple changes included here. The first is to introduce 
a cap on the size the ZED will grow the zevent list to. One million 
entries is more than enough for most use cases, and if you are 
overflowing that value, the problem needs to be addressed another 
way. The value is also tunable, for those who want the limit to be 
higher or lower. 
 
The other change is to add a kernel module parameter that allows 
snapshot creation/deletion to be exempted from the history logging; 
for most workloads, having these things logged is valuable, but for 
some workloads it produces large quantities of log spam and isn't 
especially helpful.
