Fabio M. Di Nitto eb3d49ef7d pload: make it a test service and not a public one 
pload is a performance benchmark that measures the onwire
speed of corosync.

problem is that once pload has been executed, the cluster
is basically dead.

turn pload into a test tool, by removing corosync-pload tool
and user library.

cleanup pload code to make it more readable and drop lots
of unnecessary stuff.

add test/ploadstart tool that can configure and start pload
via cmap calls.
