NIFI-3331 - TLS Toolkit - add the possibility to define SAN in issued…
… certificates
=================================================================
Issue behind this improvement is: if you have a load balancer in front of
your NiFi cluster, you may have the following issue - when accessing the UI
(secured cluster, HTTPS) you might face a certificate issue because the
certificate issuer won't match the address of the load balancer. One option to
solve this issue is to add, in addition to the node host name, the load
balancer address as Subject Alternative Names in the certificate. This should
help when deploying tools like Knox, HAProxy, etc, in front of NiFi with HTTPS
access.
This PR adds an option in the TLS Toolkit when using it in client mode. The
option allows user to define a comma separated list of domains to add as SAN
(in the example: the node and the load balancer). The domains will be added in
the CSR sent to the CA and the CA will issue a signed certificate containing
the same SAN.

> To ease the deployment of a load balancer in front of NiFi, it would be nice
> to allow users to define a SAN in certificates issued by the CA.
> To load balance the access to the UI or even with a ListenHTTP processor,
> both will cause errors with a "Host mismatch" kind of error because of
> different fqdn between nodes certificate and LB certificate. This is also
> discussed here: http://stackoverflow.com/questions/40035356/nifi-load-balancer
