[j-nsp] EX4200 JunOS Recommendation

We've now settled on 10.2R3 on our EX4200s, and EX2200s. When I tried to do "upgrades" to the "JTAC recommended releases" I managed to almost brick my EX2200's in the process. (i.e. when booting, they simply waited 15 mins for mgd to settle, amongst other nasty deadlocking situations in the boot process. Had to Ctrl-C the boot process a few times on a few different EX2200s and EX4200s on the "Juniper's Recommended Releases".

Again, this is just what is working for us....

There's a nasty known-bug with 10.2R3 on MXes, but that's not related to the EX line (I hope); as it's MPC/DPC related (and not just to Trio cards, ras =)).
