Harshavardhana 16c648b109 Remove "Connection" close instead reduce MaxConns per host (#7654) ...

This is necessary to avoid connection build up between servers
unexpectedly for example in a situation where 16 servers are
talking to each other and one server now allows a maximum of

15*4096 = 61440 idle connections

Will be kept in pool. Such a large pool is perhaps inefficient for
many reasons and also affects overall system resources.

This PR also reduces idleConnection timeout from 120 secs to 60 secs.
