ZOOKEEPER-3962: Add an .asf.yaml file

Create an .asf.yaml file to specify certain github repository settings,
such as description, topic, URL, etc. and to configure notification
settings and JIRA integration.

This file can also be later used to add automation for building the
project's website, in whole or in part.

See https://cwiki.apache.org/confluence/display/INFRA/git+-+.asf.yaml+features
for more information on available features.
