Closed Task: Implement connection resiliency name changes [1273]

As part of our API review for connection resiliency we identified a few names that we wanted to change. The changes are:

1. IExecutionStrategy to IDbExecutionStrategy
2. NonRetryingExecutionStrategy to DefaultExecutionStrategy
3. ExecutionStrategyBase to DbExecutionStrategy
4. Change all variables called action and func to operation.

We also need to change the exception messages to be more descriptive.
