[Speed] performance 0.7.0 released

Hi,

It seems like the performance benchmark suite is broken since pip 10 has been released (April 2018). The previous release was performance 0.6.1.

By the way, https://speed.python.org/ seems to be down :-(

Version 0.7.0 changes:

• python_startup: Add --exit option.

• Update requirements:

  • certifi: 2017.11.5 => 2018.10.15
  • Chameleon: 3.2 => 3.4
  • Django: 1.11.9 => 1.11.16
  • dulwich: 0.18.6 => 0.19.6
  • Genshi: 0.7 => 0.7.1
  • mercurial: 4.4.2 => 4.7.2
  • pathlib2: 2.3.0 => 2.3.2
  • psutil: 5.4.3 => 5.4.7
  • SQLAlchemy: 1.2.0 => 1.2.12
  • sympy: 1.1.1 => 1.3

• Fix issue #40 for pip 10 and newer: Remove indirect dependencies. Indirect dependencies were used to install cffi, but Mercurial 4.0 doesn't depend on cffi anymore.
