[RADIATOR] PEAP internal session resumption breaks some clients

I don't know if this is the same issue we had. It was trivial to get an 802.1x error on my non-AD laptop (for some reason I could not get it to fail with my account on an AD connected laptop). All I had to do was connect and reconnect quickly a few times in a row. We added "EAPTLS_SessionResumption 0" to our 802.1x handler and the problem went away.

I plan to dig more into the fast reconnection control behaviour, provided by the checkbox in the GUI, to see what it really does. For example, does it affect the TLS handshake.
