Migrate to java.time lib instead of joda-time

[kennknowles]

Joda-time has been used till moving to Java 8. For now, these two time libraries are used together. It will make sense finally to move everywhere to only one lib - java.time - as a standard Java time library (see mail list discussion: https://lists.apache.org/thread.html/b10f6f9daed44f5fa65e315a44b68b2f57c3e80225f5d549b84918af@%3Cdev.beam.apache.org%3E).

 

Since this migration will introduce breaking API changes, then we should address it to 3.0 release.

Would a transitional support of both in 2.x be envisionable?

If someone puts together a plan that can do it without breaking changes - or at least very few - and sends the design to the dev@ list, I'm sure it would create a useful discussion.
