perf: add asv benchmarks
Airspeed velocity (ASV) is a python framework for benchmarking Python packages
over their lifetime. The results are displayed in an interactive web frontend.
Add ASV benchmarks for mercurial that use contrib/perf.py extension that could
be run against multiple reference repositories.
The benchmark suite now includes revsets from contrib/base-revsets.txt with
variants, perftags, perfstatus, perfmanifest and perfheads.
Installation requires asv>=0.2, python-hglib and virtualenv
