[BridgeAbstract] Add loadCacheValue() and saveCacheValue() (#1380) 

* [BridgeAbstract] Add loadCacheValue() and saveCacheValue()

Bridges currently need to implement value caching manually, which
results in duplicate code and more complex bridges.

This commit adds two protected functions to BridgeAbstract that make
it possible for bridges to store and retrieve values from a temporary
cache by key.
