Replace Moshi with generated marshaller for operation json serialization

[sav007]

Part of #572

Next step is to remove Moshi from SqlNormalizedCache

@sav007 should this be made configurable. I worry that most won't care about the optimization but will care about the additional methods the request parsing generates.

@digitalbuddha well I see your point but not sure if that won't be a messy to have it both. I fell like we already have too much configs, and it was our initial idea use generation instead of Moshi.
Plus I feel like we really won't benefit of saving couple methods here. Maybe we can later optimize it a little bit when such concern raised.

Sgtm Im a big fan of removing moshi as we don't use it internally.

@digitalbuddha I completely agree.

@sav007 In this PR, I did not see you remove the dependency from the build.gradle. Did you remove it in another PR?

Are you going to remove moshi completely from this repository? It looks like it is still used: https://github.com/apollographql/apollo-android/search?utf8=%E2%9C%93&q=moshi&type=.
