Samples: add memory based load-balancing sample module
Adds a comprehensive example of a memory filter.
Logic stages:
- find the host with the least amount of free memory
- check what is the maximum vm size it can pass to
the other hosts without overloading them
- find a vm it can pass that is small enough to
run on one of the other servers.
If safe_selection = true, return the smallest vm
else try and find one that will solve the
overutilization in one migration
