Add retries to API to mitigate network error

[mcorner]

The API for getClient will fail in conditions of no, or poor networking. The nature of the SDK is that it needs to be connected to initialize and retrieve a token from execute.

Our current proposal is to create a new API that will not require networking during initialization, but will begin the process in the background. It will wait for a network connection and automatically retry if needed.

When subsequently calling execute the new API will wait for this initialization to complete up to the timeout (or infinitely if specified) and return an error if initialization or token retrieval cannot be completed in time.

We feel that this will be easier to use and relieve the burden of retries from the implementor.

Suggestions are always welcome.

Hello everyone, how is this going?

[mcorner]

We are in the process of releasing a stable version of 18.5.0 as we speak. Shortly after that we will have an 18.6.0-beta01 that will contain the new API. Android will be first, within about three weeks. Then iOS will follow shortly. We look forward to your feedback and hope that you find this API easier to integrate.
