feat: cache config from context

[Meemaw]

Add support for providing cacheConfig from context. This can be useful for a few reasons:

• Set caching config for the query
• Pass metadata to the fetch function

Note that its possible to achieve 2. today with variablesFromContext as well, but its a bit more annoying, because we don't want to send that as an actual variable to the graphql endpoint, we might want to do some conditional logic based on metadata, or send special headers.

@Meemaw This is a great idea for a feature, and after discussing internally we combined it with fetchPolicy into a new queryOptionsFromContext configuration. This lets you specify any configuration to loadQuery based on ctx and should satisfy this feature as well. We just released this in v3.0.0, can you please test this out and let us know if it works for you? Thanks!

@rrdelaney that works, thanks!
