ExponentialBackOffWithJitter algorithm not implemented as documented

[smanousos]

azure-iot-common version 1.7.1, retry_policy.js line 93:
return Math.min(constants.cMin + (Math.pow(retryCount - 1, 2) - 1) * randomJitter, constants.cMax);

This uses (retryCount - 1)^2. To match the documentation it should be 2^(retryCount - 1)

@smanousos the PR is out - the fix will be part of our next release. That was an embarassing one... thanks for finding this!! I will update this issue when the fix is checked in and again when it is released.
