Refactor: tools: Remove extern usage from crm_resource.

Some of these can be turned into members of the options struct in
crm_resource.c. Several others can just be gotten rid of. They were
being declared as extern, but were already being passed around as
function parameters everywhere.

BE_QUIET is not handled by this patch because it will be taken care of
by using pcmk__common_args_t in a later patch.
