setdiscovery: limit the size of all sample (issue4411)

Further digging on this issue show that the limit on the sample size used in
discovery never works for heads. Here is a quote from the code itself:

  desiredlen = size - len(always)
  if desiredlen <= 0:
      # This could be bad if there are very many heads, all unknown to the
      # server. We're counting on long request support here.

The long request support never landed and evolution make the "very many heads,
all unknown to the server" case quite common.

We implement a simple and stupid hard limit of sample size for all query. This
should prevent HTTP 414 error with the current state of the code.
