connectionPoolKeepAliveDuration
How long to keep idle connections alive in the OkHttp connection pool before evicting them.
The value is in seconds and must be at least 1 (OkHttp requirement). Values less than 1 will be coerced to 1.
Note: This setting affects only OkHttp's idle connection pool behavior. It does not control TCP keep-alive intervals used by the OS, the network, or PubNub servers, and it does not affect connections that are actively in use (e.g., long-poll subscribe requests).
Defaults to 300 seconds (5 minutes, OkHttp default).
