support server_idle_timeout in pgbouncer

[yee379]

various pooler args connection_pooler_* are already configurable in the operator. it would be very handy to be able to set server_idle_timeout via the operator rather than having to build a new image oneself with that parameter set.

This is a valid request and is still unfulfilled. I have ran into this problem also. In order to have a complete control over the installation, the operator should be able to handle also the pooler configuration, since for big installations, the use of pooler is paramount. Is there a plan on adding these configuration settings in the operator's crds?

Thanks in advance
