-------------------------+-------------------------------------------------
Right now, to "disable" circuit padding, we have to set consensus
parameters circpad_global_allowed_cells=1 and
circpad_global_max_padding_pct=1, which actually only sets a limit of 1%
of our traffic to be padding. Additionally, each padding cell that is
*not* sent because this limit is reached causes an info log line to be
written.
We need another way to fully disable padding, for A/B performance testing.
And we should rate limit that info log so relays logging at info don't
print a line for every single padding cell they don't send.
