A few questions around this:

- Why can't the base class just expose a GetIdentitySource() that this class
uses?
- Do we need BlimpClientContextInternal?

[xingliu, 2016/08/30 04:47:42]

Moved this to base class, and rename BlimpClientContextInternal to
BlimpPreferencesDelegate in Java, removed c++ interface. The Java one is needed
because BlimpClientContextImpl depends on settings and glue things together, so
settings can't depend on context impl directly.
