Enable connection_keepalive by default

Browse Source 
Enabling the feature by default prevents the master connection from dying
during times when there are very little or no writes. Having a modest ping
interval of 300 seconds serves to minimize the amount of extra work that
both MaxScale and the server have to do while still keeping the
connections in good shape.

### Readwritesplit
#### `connection_keepalive`
The default value of `connection_keepalive` is now 300 seconds. This prevents
the connections from dying due to wait_timeout with longer sessions. This is
especially helpful with pooled connections that stay alive for a very long time.
