Admin Page: no more option to switch Primary user

[jeherve]

In Jetpack 4.2, it is possible for any connected site admin to change the Jetpack primary user to another connected site admin. It's important for people doing client work for example, wanting to switch ownership of the site to another admin account.

That option doesn't exist on Jetpack 4.3, and the old "My Jetpack" page isn't accessible anymore.

Could we add the option back to the Connection settings card?

We will add this, but not really enough time for this release. Still needs to be designed and thought out. Punting to 4.4
