Major Description
Ratis use the security materials passed by Ozone to establish tls connection. Currently, there are two ways to configure tls. For cert, one is cert file based, another is cert objects. For privateKey, one is private key file, another is private key object.
This task aims to support the third way to configure tls. That is, pass in a KeyManager and trustManager object for key and cert. The motivation of this is we want to support certificate dynamic reloading in Ozone when certificate is going to expire and a new certificate is generated to replace the old one.
