Details on the issue fix or feature implementation

• Simplify property names when the name is clear (i.e. HedgingDelay -> Delay)
• Rename RetryBackoffType to DelayBackoffType to make it more universal as it can be used by other strategies later.
• Rename RetryCount to MaxRetryAttempts to make it alligned with hedging (MaxHedgingAttempts) and to make it clear that retry strategy can exit sooner than that.
• MaxHedgingAttempts with value 1 is now valid. (the initial attempt does not count, similar to how retry strategy works)
