feat(sdk): testing framework for puts (state transitions) in rs-sdk

[lklimek]

Issue being fixed or feature implemented

For the rs-sdk testing, we assume that each feature must have relevant test implemented. Current rs-sdk test framework doesn't support testing of Puts (what includes state transitions).

What was done?

In this PR, we define a Wallet trait that provides access to wallet features. On top of that, we include improvements to ContextProvider (formerly known as QuorumInfoProvider).

How Has This Been Tested?

Integrated with rs-platform-explorer (not pushed) - it builds. :)
