Reconnect Policy

[cvybhu]

Currently when a connection breaks we attempt to reconnect with a fixed 8 second cooldown.

Reconnection strategy should be configurable by the user.
DataStax Java Driver has a configurable reconnection policy, we should implement something similar in this driver.

ReconnectPolicy could be a trait and a Box<dyn ReconnectPolicy> could be included in SessionConfig and ConnectionConfig. Then ConnectionKeeperWorker would use it to decide when to schedule reconnect attempts.
