Make domain and data modules dependent on javax.inject instead of dagger 2

[DmitriyZaitsev]

Dagger 2 has implicit dependency:

+--- com.google.dagger:dagger:2.0.2
|    \--- javax.inject:javax.inject:1

Domain and Data modules don't depend on any class from the Dagger 2 API.
They need only @Inject annotation, so it makes no sense to have the entire library in classpath.

@android10 Could this PR be merged? Is there a reason against this PR?

[android10]

@Rainer-Lang hold your horses. There is another PR being cook and after we finish a discussion I will test this and merge. Patience my friend. 😄

[Rainer-Lang]

@android10 I like horses :-D
Thanks for response.

[android10]

@Rainer-Lang haha nice! The PR is valid but give some time to merge it :)

[android10]

@DmitriyZaitsev can you squash the commits so I merge afterwards? Sorry for the delay on this.

[DmitriyZaitsev]

@android10, do you insist on squashing? I believe it's better to have two "atomic" independent commits.

[android10]

@DmitriyZaitsev I like to have one commit per PR. It is easy when you check history on master and in case of a potential rollback you don't deal with "atomic" commits.

Also, by squashing you can keep all the atomic comments anyway.

[DmitriyZaitsev]

@android10, done!

• squashed commits;
• rebased onto master

@DmitriyZaitsev thanks for the contribution!
