Add configuration option for RedisConnectionPool lease timeout
With RedisConnectionPool a timeout is provided to prevent infinite loops of retrying connections, but right now it is hardcoded to 60 seconds.
Users of downstream projects such as Vapor are noticing a "regression" of sorts, as previously EventLoopFutures would fail immediately if a connection was not made available.
RedisConnectionPoolinitializer that still defaults to 60 seconds
- Change: RedisConnectionPool to use the new parameter if available to offset a deadline from "now"
Users can now configure the connection pool to fail immediately if connections are not available.
