maximumDelay for exponential retry policy always throws an error (v8.x.x)

[jkester1986]

The code is:

       else if (this.maximumDelay)
                    throw new Error('Maximum delay can not be set more than 150 seconds for retry');

which means if any maximumDelay is set, then the error will throw

suggested fix:

       else if (this.maximumDelay > 150)
                    throw new Error('Maximum delay can not be set more than 150 seconds for retry');
