Retry 5xx Errors

[LucienHH]

This PR exponentially increases the retry delay and removes the retryCount parameter. The exponential increase in retry delay is intended to help mitigate intermittent errors that can occur when using the Realms API.

The first retry will have a delay of 1 second (2^0 1000). The second retry will have a delay of 2 seconds (2^1 1000). The third retry will have a delay of 4 seconds (2^2 1000). The fourth retry will have a delay of 8 seconds (2^3 1000). The fifth and final retry will have a delay of 16 seconds (2^4 * 1000).

More than 30 seconds is too long. Should be closer to 10-20 seconds max per request to not make actual errors take an long time to surface.

Lets just do 4 tries then. From testing it seems that the 4th retry is enough and responds ok.

Can we merge this for a release @extremeheat ?
