Cleanups in ChromotingClient

Cleanups in ChromotingClient

1. Moved creation of ConnectionToHost to ChromotingClient. Previously
   ConnectionToHost had to be passed in the constructor.
2. Authentication now is created outside of ChromotingClient. This
   allowed to remove ClientConfig struct (it was used mostly to
   pass authentication parameters). This will also allow passing
   a fake authenticator for tests.
3. Removed ClientConfig.

+dcaiafa,
Dan, FYI, I made some changes in the iOS client. I think it should compile after
this change, but I didn't try. Let me know if it breaks and you need help
resolving the problem.

I'll try the changes as soon as they land. I'll let you know if I run into
nontrivial problems.
