Problem Statement: Currently Ranger can communicate to SSL enabled MySQL server but only if 2-way SSL config is provided, Ranger should support for MySQL configured in Standard SSL(one-way) mode.
Proposed Solution: For mutual SSL (2-way) support keystore is required, which is currently mandatory even if user want to connect to MySQL by using Standard(1-way). Proposed solution requires changes in install.properites to have a property 'db_ssl_auth_type' which can have value '1-way' or '2-way'. Default value shall be '2-way'. In case of '1-way', support keystore won't be required however truststore is mandatory.
