Jan Friesse d05636b738 totemconfig: Remove support for 3des 
Triple DES is considered as a "weak cipher" since 2016 so there is
really no need to support it in the corosync. Thanks to bug in
Corosync/Knet/NSS which caused 3des to not work at all,
no matter what library was used, we can just remove support for 3des
without braking the compatibility.

Also fix coroparse so:
- totem.crypto_type is removed (this is 1.x construct which was not used
even in 2.x)
- Add checking of totem.crypto_model.
- Enumarate possible values for crypto_model, crypto_cipher and
crypto_hash error messages
