fuelclient commands

There are three new fuel2 commands that work with API endpoints and allow you to set, get and delete cpu pinning values for nodes, here are example uses:

fuel2 cpu-pinning-set --node 32 --vrouter_cores 1,3 --nova_cores 18,20,22,8

fuel2 cpu-pinning-get --node 32

fuel2 cpu-pinning-del --node 32
