Description:
The name of the SocketFactory interface changed from com.mysql.jdbc.SocketFactory to com.mysql.cj.api.io.SocketFactory. This means that a single library can't be compatible with both Connector/J 5.x and Connector/J 6.x. 

This requires separate artifacts for different Connector/J versions and the users must make sure they use the right one. If they don't, Connector/J will not be able to load the socket factory and will continue as if one wasn't specified.

How to repeat:
Try using an existing custom socket factory implementation with Connector/J 6.x

Suggested fix:
Please include a dummy com.mysql.jdbc.SocketFactory interface that extends  com.mysql.cj.api.io.SocketFactory to avoid breaking SocketFactory users.

Added the following entry to the C/J 8.0.11 changelog:

"Name change of the com.mysql.jdbc.SocketFactory interface to com.mysql.cj.api.io.SocketFactory caused backward incompatibility for older Connector/J applications. The old interface has now been reimplemented to avoid the incompatibility."
