- update to 3.7.0:
* Use a tty for `docker` and `docker_image` hooks when
`--color` is specified.
* Fix `fail_fast` for individual hooks stopping when previous
hooks had failed.
* The per-hook behaviour of `fail_fast` was fixed. If you want
the pre-3.7.0 behaviour, add `fail_fast: true` to all hooks
before the last `fail_fast` hook.

- Specify a Group tag for Leap and SUSE Linux Enterprise
CPAN initialisation also on SUSE Linux Enterprise.
- Fix build for multiple python flavors
* Add conda as a new language.
* Remove python2 / python3.5 support. Note that pre-commit still
supports running hooks written in python2, but pre-commit itself
* Removed pcre language, use pygrep instead.
* Replace aspy.yaml with sort_keys=False.
* Add support for perl.
* Fix python healthy() check when python executable goes missing.
