progress: remove progress.estimate config
It was introduced by 98e4d39 ("progress: add speed format" 2011-5-9) and was
intended to hide ETA information for the first few seconds.
Later 5d261fd ("progress: add a changedelay to prevent parallel topics from
flapping (issue2698)" 2011-6-23) introduced `changedelay` config which hides
the entire progress bar for the first few seconds. So `progress.estimate` seems
somehow duplicated feature-wise. Since it's experimental and duplicated, let's
just remove it. This makes the next patch simpler - it no longer needs to make
sure `starttimes` is the real start time.

'''measure performance of Mercurial commands Using ``hgperf`` instead of ``hg`` measures performance of the target Mercurial command. For example, the execution below measures performance of :hg:`heads --topo`:: $ hgperf heads --topo All command output via ``ui`` is suppressed, and just measurement result is displayed: see also "perf" extension in "contrib". Costs of processing before dispatching to the command function like below are not measured:: - parsing command line (e.g. option validity check) - reading configuration files in But ``pre-`` and ``post-`` hook invocation for the target command is measured, even though these are invoked before or after dispatching to the command function, because these may be required to repeat execution of the target command correctly.
