kerberos: authentication between client and broker (apache#3821)
Fixes apache#3652 **Motivation** Currently both Zookeeper and BookKeeper could be secured by using Kerberos, It would be good to support Kerberos in Pulsar Broker and Client. This is the sub-task for issue in apache#3491 to support Kerberos in Pulsar Broker and Client. Will add proxy and web resource support in following prs. The Kerberos authentication is similar to that in Zookeeper and BookKeeper, which leverage SASL and GSSAPI, so reused some of the code there. PR apache#3658 is the first version of PR before apache#3677 . **Changes** provide both client and broker side support for authentication api; add unit test.
