The execution of the setFCV command includes the interruption of sessions involving nodes with different binary versions - and causes the abortion of any ongoing transaction associated.

It has been observed that transactions running on a local client (such as the one introduced with SERVER-68926) are also interrupted.

The objective of this ticket is

• to confirm whether local transactions need to be interrupted while serving a setFCV command - and if not, modify the code to avoid that.
• act accordingly on the TODO comments in the source code that reference this ticket
