IdempotenceAwareRetryPolicy Class

A retry policy that avoids retrying non-idempotent statements.

In case of write timeouts this policy will always return Rethrow if the statement is considered non-idempotent (see IsIdempotent). For all other cases, this policy delegates the decision to the child policy.
