When server and management are at different ports, and when server
requires TLS client authentication, then there is no simple method to
disable TLS client authentication for management port.
This commit adds an additional "none" option to ssl.client-auth.
Example:
server.port=8080
server.ssl.enabled=true
server.ssl.client-auth=need
management.server.port=8081
management.server.ssl.enabled=true
management.server.ssl.client-auth=none
