Please expose context in DatabaseConfiguration class

@hideki Can you please allow us to getContext() (make it public) in the DatabaseConfiguration class? There are classes where I store a config instance and I also need context and makes no sense to store Context twice. You already have a getter in there, just need to make it public.

An API change like that would need to be cross-platform, and needs review (@pasin). We can consider it for 2.1.

Thank you.
(Oh. By the way, when is 2.1…:joy:)

Fairly soon after 2.0 — there are some high priority features we had to cut late in the cycle (encryption, P2P) and the 2.1 release is to deliver those ASAP.
