obmcutil is slow, nonsensical output

[Norman James]

obmcutil was intended as a lab debug tool only.  It is simply a lookup of
shortcuts to the dbus calls.  It prints out whatever the dbus call returns.
All of the slowness is due to python importing several libraries which is
slow because the CPU is already highly utilized.   Brad looked into this at
one point and collected some data.

We see the same behavior on the Barreleye servers, the obmcutil is quite
slow but we've gotten used to it. The poweron and poweroff commands usually
return either this message or a python backtrace if the backend dbus
services are still warming up.

root at palmetto:~# time obmcutil 2>&1 > /dev/null

real    0m3.301s
user    0m3.030s
sys     0m0.230s

root at palmetto:~# obmcutil poweron
 = None

The above is really confusing as to what is actually going on... does
that mean success? Does that mean there's no power? Does that mean no
action was taken?
