Need for satisfiability check in the match function signature

[vsoch]

From my notes:

We need way to specify we want satisfiability check in the match function signature.

My best guess (based on knowing the Go bindings) is that the match function signature might be in the resource API, here?

flux-sched/resource/reapi/bindings/c/reapi_cli.cpp

Lines 93 to 97 in fe872c8

	extern "C" int reapi_cli_match_allocate (reapi_cli_ctx_t *ctx,
	bool orelse_reserve, const char *jobspec,
	uint64_t *jobid, bool *reserved,
	char **R, int64_t *at, double *ov)
	{

And this might warrant more discussion about how the current design (with all the booleans) might be something else to warrant more flexibility.
