This commit updates IkeSessionParamsUtils to be able
to encode/decode IkeSessionParams with IKE_OPTION_REKEY_MOBILITY,
IKE_OPTION_AUTOMATIC_ADDRESS_FAMILY_SELECTION and
IKE_OPTION_AUTOMATIC_NATT_KEEPALIVES.
This commit can also maintain compatibility with older T IPsec
modules that do not support the two IKE_OPTION_AUTOMATIC_ options
