Initialize the encoding process. Removes the
{@link CasViewConstants#MODEL_ATTRIBUTE_NAME_PRINCIPAL_CREDENTIAL}
and
{@link CasViewConstants#MODEL_ATTRIBUTE_NAME_PROXY_GRANTING_TICKET}
from the authentication attributes originally and into a cache object, so it
can later on be encrypted if needed.

@param attributes the new encoded attributes
@return a map of attributes that are to be encoded and encrypted
