Missing getMemo functionality in WorkflowInfo

[mobiletoly]

Expected Behavior

WorkflowInfo interface should have getMemo() to return memos

Steps to Reproduce the Problem

WorkflowOptions.Builder has method .setMemo that allows setting memos. There is no corresponding WorkflowInfo method to retrieve this information from running workflow. This makes memo pretty useless when using Temporal Java SDK.

Version
