This change adds a configuration for commitlint - a tool designed to
enforce a particular commit message style - and run it as part of Git's
commit-msg hook. This validates commits immediately after the editor has
been exited, and the configuration is derived from the configuration we
provide to Commitizen.
While the configuration provided suggests a maximum header and body
length, neither of these are hard errors. This is to accommodate the
occasional commit where it may be difficult or impossible to comply
with the length requirements (for example, with a particularly long
scope, or a long URL in the message body).
