Schemas: pephubclient should be able to return schema objects.

Related to pepkit/pephub#271

if we serve schemas in pephub, then I would like to get fields of schema using pephubclient. ... Or download schema.

If schemas are in pephub, then

But there has to be some process where we “approve them” right?

I think:

we don't need it, right ?
we can add flag: approved by pephub admin

Seems like this should be an issue in pephubclient ? As per pepkit/pephub#271 ... we will soon have endpoints to retrieve schemas
