chore: upgrade to @apollo/client 3

sarfata commented 4 years ago

remove support for custom ApolloProvider. This was required to support apollo-react-hooks but this library is deprecated and hooks are now built in @apollo/client. (I am the one who added this)
rewrote the tests to use hooks as the HOC components are not built-in @apollo/client anymore
modernize fetchTypeDefs to fetch via graphql-tools (instead of apollo-link-http/HttpLink which has changed and is not compatible with introspectSchema)
update tests to pass on errors: apollo does not add the prefix "GraphQL Error" anymore
bumped major version number as people should probably only upgrade if they have done the same dependencies update on their project

TBD: Should we also remove support for client resolvers? The test with one fails and they look deprecated (https://www.apollographql.com/docs/react/local-state/local-resolvers/) @sliptype Can you chime in on this? You are the one who added it.

Is this ready to merge/deploy or is there anything else you wanted to change?

I think it's all ready to go and I am using it on one project where it's working well.
