key: Make ed_key_init_from_file() take an or_options_t

Browse Source 
Part of #27215, we need to call the ed_key_init_from_file function during
option_validate() which is before the global_options variable is set.

This commit make ed_key_init_from_file() stop using get_options() and instead
now has a or_options_t parameter.
