Revisit buildd-monitor design

[Celso Providelo]

As per bjorn comments, this code lacks tests and it's badly designed in some parts, like:

{{{
args= request[:1]
d=maybeDeferred(meth, args)
...
def cmd_reset(self, args)
}}}

We should something like this:

{{{
d = maybeDeferred(meth, *args)
...
def cmd_reset(self, build_id=None)
}}}

[Celso Providelo (cprov)]

Reduce the priority since the code is almost unnecessary in production.

buildd-monitor is gone.
