[WIP] Use ApolloClient 2.0 and new API of ApolloAngular

[kamilkisiela]

Updated:

• Angular Material
• Flex Layout
• Angular v5
• ApolloClient 2.0
• ApolloAngular (my local release - @kamilkisiela/* scope)

Issues:

• [ ] @angular/flex-layout - uses nightly build, non of releases supports Angular v5 (npm install doesn't work with those nightly builds...)
• [ ] Because of some mismatch in version range of @types/graphql yarn installs older version that doesn't have operation Line 15 of src/apollo/link.ts
• [ ] BUG: readQuery() returns the result instead of {result, complete} #2308 in apollo-client
